实现的方法：
1.在父级项目中 或者 每个微服务都引用的项目中添加实体类Resource
2.在父级项目中 或者 每个为服务都引用的项目中写一个工具类，作用是用来获取请求资源
3.在每一个微服务的启动类添加注解@RestController ,并且写一个请求方法调用 工具类的请求资源的方法
4.将获取到的JSON字符串 保存在文件中
5.最后,在需要存储这些信息到数据库中的对应微服务 提供一个请求方法，参数就传递这一个一个的JSON字符串，而请求方法做的事情就是解析JSON，并批量保存到对应数据表中
1.先提供一个状态这些结果的实体Resource.java
package com.pisen.cloud.luna.core.utils.beans;public class Resource { public static final Integer GET_RESOURCE = 1; public static final Integer OTHER_RESOURCE = 2; public static final Integer ENABLE = 1;//启用 public static final Integer DISENABLE = 0;//禁用 private String path;//资源URL private String name;//资源名 private String msName;//资源所属微服务 private Integer type;//资源类型 1代表数据资源 2代表功能资源 private Integer enable;//是否启用 0 禁用 1 启用 private String user;//资源被使用对象 private String remark;//资源备注 public String getPath() {
return path;
} public void setPath(String path) {
this.path = path;
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public String getMsName() {
return msName;
} public void setMsName(String msName) {
this.msName = msName;
} public Integer getType() {
return type;
} public void setType(Integer type) {
this.type = type;
} public String getUser() {
return user;
} public void setUser(String user) {
this.user = user;
} public String getRemark() {
return remark;
} public void setRemark(String remark) {
this.remark = remark;
} public Resource(String path, String name, String msName, Integer type, String user, String remark,Integer enable) {
this.path = path;
this.name = name;
this.msName = msName;
this.type = type;
this.user = user;
this.remark = remark;
this.enable = enable;
}
}
2.同样在 所有微服务都能引用到的 地方 提供一个工具类MappingResourceUtil.java
package com.pisen.cloud.luna.core.utils;import com.pisen.cloud.luna.core.utils.beans.Resource;
import com.pisen.cloud.luna.core.utils.beans.ResourceConfig;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.BeanFactoryUtils;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.mvc.condition.PatternsRequestCondition;
import org.springframework.web.servlet.mvc.condition.RequestMethodsRequestCondition;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;public class MappingResourceUtil { /**
* 获取本服务下 所有RequestMapping标记的资源信息
* @param request
* @param msName 需要传入ms-name 微服务别名
* @return
*/
public static List<Resource> getMappingList(HttpServletRequest request,String msName){
ServletContext servletContext = request.getSession().getServletContext();
if (servletContext == null)
{
return null;
}
WebApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(servletContext); //请求url和处理方法的映射
List<Resource> requestToMethodItemList = new ArrayList<Resource>();
//获取所有的RequestMapping
Map<String, HandlerMapping> allRequestMappings = BeanFactoryUtils.beansOfTypeIncludingAncestors(appContext,
HandlerMapping.class, true, false); for (HandlerMapping handlerMapping : allRequestMappings.values())
{
//本项目只需要RequestMappingHandlerMapping中的URL映射
if (handlerMapping instanceof RequestMappingHandlerMapping)
{
RequestMappingHandlerMapping requestMappingHandlerMapping = (RequestMappingHandlerMapping) handlerMapping;
Map<RequestMappingInfo, HandlerMethod> handlerMethods = requestMappingHandlerMapping.getHandlerMethods();
for (Map.Entry<RequestMappingInfo, HandlerMethod> requestMappingInfoHandlerMethodEntry : handlerMethods.entrySet())
{
RequestMappingInfo requestMappingInfo = requestMappingInfoHandlerMethodEntry.getKey();
HandlerMethod mappingInfoValue = requestMappingInfoHandlerMethodEntry.getValue(); PatternsRequestCondition patternsCondition = requestMappingInfo.getPatternsCondition();
String requestUrl = patternsCondition.getPatterns() != null && patternsCondition.getPatterns().size()>0 ?
patternsCondition.getPatterns().stream().collect(Collectors.toList()).get(0).toString() : null; RequestMethodsRequestCondition methodCondition = requestMappingInfo.getMethodsCondition();
String requestType = methodCondition.getMethods() != null && methodCondition.getMethods().size()>0 ?
methodCondition.getMethods().stream().collect(Collectors.toList()).get(0).toString() : null; if (requestType == null){
continue;
} String controllerName = mappingInfoValue.getBeanType().toString();
String requestMethodName = mappingInfoValue.getMethod().getName();
Class<?>[] methodParamTypes = mappingInfoValue.getMethod().getParameterTypes(); String name = getResourceName(requestType,requestMethodName);
Integer type = getType(requestType);
String path = msName+":"+requestUrl;
String user = getUser(requestUrl);
Integer enable = Resource.ENABLE;
Resource resource = new Resource(path,name,msName,type,user,null,enable); requestToMethodItemList.add(resource);
}
break;
}
} return requestToMethodItemList;
} /**
* GET 代表数据资源 1
* 其他 代表功能资源 2
* @param type
* @return
*/
public static Integer getType(String type){
return "GET".equals(type) ? Resource.GET_RESOURCE : Resource.OTHER_RESOURCE;
} /**
* 按照请求地址和请求方法 获取资源名称
* @param requestType
* @param requestMethodName
* @return
*/
public static String getResourceName(String requestType,String requestMethodName){
requestMethodName = requestMethodName.toLowerCase();
if ("GET".equals(requestType)){
return ResourceConfig.GET+requestMethodName;
}else{
if (requestMethodName.contains("page")){
return ResourceConfig.PAGE+requestMethodName;
}
if(requestMethodName.contains("list")){
return ResourceConfig.GET+requestMethodName+ResourceConfig.LIST;
}
if (requestMethodName.contains("insert")){
return ResourceConfig.INSERT+requestMethodName;
}
if (requestMethodName.contains("delete")){
return ResourceConfig.DELETE+requestMethodName;
}
if (requestMethodName.contains("update")){
return ResourceConfig.UPDATE+requestMethodName;
}
if (requestMethodName.contains("add")){
return ResourceConfig.ADD+requestMethodName;
}
if (requestMethodName.contains("enable")){
return ResourceConfig.ENABLE+requestMethodName;
}
if (requestMethodName.contains("init")){
return ResourceConfig.INIT+requestMethodName;
}
if (requestMethodName.contains("verify")){
return ResourceConfig.VERIFY+requestMethodName;
}
if (requestMethodName.contains("find")){
return ResourceConfig.FIND+requestMethodName;
} return requestMethodName; }
} /**
* 获取资源使用者身份
* @param requestUrl
* @return
*/
public static String getUser(String requestUrl){
if (StringUtils.isNotBlank(requestUrl)){ String[] pathArr = requestUrl.split("/"); if (pathArr.length > 0 ){
if ("ten".equals(pathArr[1])){
return ResourceConfig.USER_TEN;
}
if ("admin".equals(pathArr[1])) {
return ResourceConfig.USER_ADMIN;
}
if ("member".equals(pathArr[1])){
return ResourceConfig.USER_MEMBER;
}
if ("free".equals(pathArr[1])){
return ResourceConfig.USER_FREE;
}
if ("dealer".equals(pathArr[1])){
return ResourceConfig.USER_DEALER;
}
}
}
return "未知使用者"; }}
以及一个配置类:ResourceConfig.java
package com.pisen.cloud.luna.core.utils.beans;public class ResourceConfig { //资源名说明关键字
public final static String GET = "获取";
public final static String INIT = "初始化操作";
public final static String VERIFY = "校验";
public final static String DELETE = "删除操作";
public final static String PAGE = "分页查询";
public final static String INSERT = "插入操作";
public final static String FIND = "查找";
public final static String UPDATE = "更新操作";
public final static String ENABLE = "启用判断";
public final static String ADD = "添加操作";
public final static String LIST = "集合"; //各微服务网关别名 public final static String MS_ACCOUNT = "ms-account";
public final static String MS_ADMIN = "ms-admin";
public final static String MS_DEALER = "ms-dealer";
public final static String MS_EVENT_CENTER = "ms-event-center";
public final static String MS_GOODS = "ms-goods";
public final static String MS_INTEGRAL = "ms-integral";
public final static String MS_MEMBER = "ms-member";
public final static String MS_CODE = "ms-code";
public final static String MS_TEN = "ms-ten";
public final static String MS_ZHONGQI = "ms-zhongqi";
public final static String MS_PAPER = "ms-paper";
public final static String MS_TASK_LIST = "ms-task-list"; //各使用者角色
public final static String USER_ADMIN = "管理员";
public final static String USER_TEN = "租户";
public final static String USER_DEALER = "经销商";
public final static String USER_FREE = "所有人";
public final static String USER_MEMBER = "会员";}
3.然后就可以在每一个微服务的启动类上加注解,加下面这段代码,然后启动这个微服务,访问就能拿到这个微服务下的所有请求资源 为一个JSON字符串了
举个例子,我现在获取这个微服务的所有请求资源:【红色部分就是 任意粘贴到每一个启动类的代码】【紫色部分就是需要更改的每一个不同微服务的不同服务名】
package pisen.cloud.luna.ms.account;import com.alibaba.fastjson.JSON;
import com.pisen.cloud.luna.core.result.AjaxResult;
import com.pisen.cloud.luna.core.utils.MappingResourceUtil;import com.pisen.cloud.luna.core.utils.beans.Resource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.feign.EnableFeignClients;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.servlet.http.HttpServletRequest;
import java.util.List;@EnableDiscoveryClient
@SpringBootApplication
@EnableFeignClients
@EnableTransactionManagement // 启注解事务管理，等同于xml配置方式的
@RestController
public class PisenLunaMSAccountApp { public static void main(String[] args) {
// String str = MappingResourceUtil.getMappingList(PisenLunaMSAccountApp.class); SpringApplication.run(PisenLunaMSAccountApp.class, args);
} @RequestMapping("/test/index")
public AjaxResult<String> getAccout(HttpServletRequest request){
AjaxResult<String> result = new AjaxResult<>();
List<Resource> list = MappingResourceUtil.getMappingList(request,"ms-account"); String account = JSON.toJSONString(list); result.initTrue(account);
return result;
}
}
然后启动本微服务后，postman请求即可：
4.将请求到的 JSON字符串，保存下来一会用
使用postman请求下来的字符串 如上 会有\
保存下来如下:
记得最后在编辑器中将\全部替换掉 否则 JSON转化会出问题
在sublime text中
将所有的\”替换成 “即可
替换完成 内容如下:
5.最后，在想要将这些JSON字符串转化为数据库数据的微服务中，提供一个批量插入的方法，然后将JSON字符串当作参数传入即可[controller中的请求方法]
@Override
@RequestMapping("batchInsert2")
public AjaxResult<List<Resource>> batchInsert2(@RequestBody String json) {
AdminUser adminUser = AdminUser.createFeignUser("insert-resource");
String adminUid = adminUser.getUid();
AjaxResult<List<Resource>> res = new AjaxResult<>();
json = JSONObject.parseObject(json).getString("json");
List<Resource> list = JSONArray.parseArray(json,Resource.class);
for (Resource resource : list) {
resource.setEnabledFlag(1);
resource.setUid(LunaIDUtil.uid());
resource.setCreateDate(new Date());
resource.setUpdateDate(new Date());
resource.setUpdateId(adminUid);
resource.setCreateId(adminUid);
resource.setUrl(resource.getPath());
}
sysUserService.batchInsert(list);
res.initTrue(list);
return res;
}
Resource如下:
package com.pisen.cloud.luna.ms.tenement.base.domain;import javax.persistence.*;
import java.util.Date;@Entity
@Table(uniqueConstraints = {
@UniqueConstraint(columnNames = "uid")
})
public class Resource { @Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;// 主键 自增 @Column(nullable = false)
private String uid; //业务主键 @Column(nullable = false, updatable = false)
private Date createDate = new Date();// 创建时间 @Column(nullable = false)
private Date updateDate = new Date();// 修改时间 @Column(nullable = false)
private String createId;// 创建人id @Column(nullable = false)
private String updateId;// 修改人id private Integer enabledFlag;// 是否启用 1启用 0禁用 private String remark;// 备注 private String name;//资源名 private String url;//资源URL private String path;// 资源URL private String msName;//资源所属微服务 private Integer type;//资源类型 1代表数据资源 2代表功能资源 public Long getId() {
return id;
} public void setId(Long id) {
this.id = id;
} public String getUid() {
return uid;
} public String getPath() {
return path;
} public void setPath(String path) {
this.path = path;
} public void setUid(String uid) {
this.uid = uid;
} public Date getCreateDate() {
return createDate;
} public void setCreateDate(Date createDate) {
this.createDate = createDate;
} public Date getUpdateDate() {
return updateDate;
} public void setUpdateDate(Date updateDate) {
this.updateDate = updateDate;
} public String getCreateId() {
return createId;
} public void setCreateId(String createId) {
this.createId = createId;
} public String getUpdateId() {
return updateId;
} public void setUpdateId(String updateId) {
this.updateId = updateId;
} public Integer getEnabledFlag() {
return enabledFlag;
} public void setEnabledFlag(Integer enabledFlag) {
this.enabledFlag = enabledFlag;
} public String getRemark() {
return remark;
} public void setRemark(String remark) {
this.remark = remark;
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public String getUrl() {
return url;
} public void setUrl(String url) {
this.url = url;
} public String getMsName() {
return msName;
} public void setMsName(String msName) {
this.msName = msName;
} public Integer getType() {
return type;
} public void setType(Integer type) {
this.type = type;
}
}
批量插入方法 使用JPA的save()即可，使用mybatis的批量插入也可以
使用postman请求地址如下:【注意请求的格式，post请求，参数格式也需要注意】
完成！！！！！！！
===========================================================================================
收集到另外一种方法，更简单：
直接在controller中加上一个方法，请求即可：
@RequestMapping(value="getUrlMapping")
public Object getUrlMapping(HttpServletRequest request) {
WebApplicationContext wc = getWebApplicationContext(request.getSession().getServletContext());
RequestMappingHandlerMapping rmhp = wc.getBean(RequestMappingHandlerMapping.class);
Map<RequestMappingInfo, HandlerMethod> map = rmhp.getHandlerMethods();
for (Iterator<RequestMappingInfo> iterator = map.keySet().iterator(); iterator
.hasNext();) {
RequestMappingInfo info = iterator.next();
System.out.println(info.getConsumesCondition());
System.out.println(info.getCustomCondition());
System.out.println(info.getHeadersCondition());
System.out.println(info.getMethodsCondition());
System.out.println(info.getParamsCondition());
System.out.println(info.getPatternsCondition());
System.out.println(info.getProducesCondition()); System.out.println("==="); HandlerMethod method = map.get(info);
System.out.println(method.getMethod().getName() + "--");
System.out.println();
}
return null;
}
