Springboot & Mybatis 构建restful 服务五

Springboot & Mybatis 构建restful 服务五

1 前置条件

• 成功执行完Springboot & Mybatis 构建restful 服务四

2 restful service 整合 swigger ui 自动生成 API

1）修改 POM.xml文件

添加依赖

        <dependency>

            <groupId>io.springfox</groupId>

            <artifactId>springfox-swagger2</artifactId>

            <version>2.2.2</version>

        </dependency>

        <dependency>

            <groupId>io.springfox</groupId>

            <artifactId>springfox-swagger-ui</artifactId>

            <version>2.2.2</version>

        </dependency>

2）修改 application.properties

src/main/resources/application.properties

server.context-path=/accountbalance

3）新建Swagger2Configuration.java

​ src/main/java/com/serena/config/Swagger2Configuration.java

package com.serena.config;

​

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;

import springfox.documentation.builders.PathSelectors;

import springfox.documentation.builders.RequestHandlerSelectors;

import springfox.documentation.service.ApiInfo;

import springfox.documentation.spi.DocumentationType;

import springfox.documentation.spring.web.plugins.Docket;

import springfox.documentation.swagger2.annotations.EnableSwagger2;

​

@Configuration

@EnableSwagger2

public class Swagger2Configuration {

    @Bean

    public Docket buildDocket() {

        return new Docket(DocumentationType.SWAGGER_2)

                .apiInfo(buildApiInf())

                .select()

                .apis(RequestHandlerSelectors.basePackage("com.serena.controller"))//要扫描的API(Controller)基础包

                .paths(PathSelectors.any())

                .build();

    }

    private ApiInfo buildApiInf() {

        return new ApiInfoBuilder()

                .title("Spring Boot中使用Swagger2 UI构建AccountBalance API文档")

                .contact("psj")

                .version("1.0")

                .build();

    }

}

4）修改 SY,添加注解

​ src/main/java/com/serena/controller/SY.java

package com.serena.controller;

import java.util.List;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import com.serena.entity.SettleAccount;

import com.serena.service.ISY;

import io.swagger.annotations.Api;

import io.swagger.annotations.ApiImplicitParam;

import io.swagger.annotations.ApiImplicitParams;

import io.swagger.annotations.ApiOperation;

​

@Api("查找账户余额")

@RestController

public class SY {

​

    @Autowired

    private ISY iSY;

    private static Logger logg = LoggerFactory.getLogger(SY.class);

    @ApiOperation("通过账户编号查询账户余额等信息")

    @ApiImplicitParams({

        @ApiImplicitParam(name="accountCode",required=true,dataType="String",paramType="Path")

    })

    @RequestMapping(value="/account/{accountCode}",method = RequestMethod.GET)

    public SettleAccount selectOne(@PathVariable("accountCode")String accountCode){

        logg.info("select account by accountCode,accountCode = {}",accountCode); 

        SettleAccount settleAccount  = iSY.selectByAccountCode(accountCode);

        if(settleAccount == null)

            logg.warn("not found account");

            return settleAccount;

    }

    @ApiOperation("查询所有账户余额等信息")

    @RequestMapping(value="/accounts",method = RequestMethod.GET)

    public List<SettleAccount> selectAll(){

        List<SettleAccount> list = null;

        logg.info("select all accounts"); 

        list = iSY.selectAccounts();

        if(list == null)

            logg.warn("not found accounts");

        return list;

    }

    @ApiOperation(value="查询所有账户余额等信息，并导出在 excel 表格中")

    @ApiImplicitParams({

        @ApiImplicitParam(name="fileName",required=true,dataType="String",paramType="Path")

    })

    @RequestMapping(value="/accountsfile/{fileName}",method = RequestMethod.GET)

    public boolean wSelectAll(@PathVariable("fileName")String fileName){

        logg.info("write a file that select accounts "); 

        List<SettleAccount> list = null;

        boolean flag = false;

        list = iSY.selectAccounts();

        if(list == null)

            logg.warn("not found accounts");

        else{

            flag = iSY.createExcel(list, fileName);

        }

        return flag;

    }

}

5）在终端输入如下测试指令：

#cd 项目所在目录

cd /Users/psj/Documents/pro/xm/AccountBalance

mvn clean package

cd target

mkdir /Users/psj/Desktop/t/

#将 tar 包复制到自己指定目录(/Users/psj/Desktop/t/)

cp AccountBalance-0.0.1-SNAPSHOT.tar /Users/psj/Desktop/t/

#cd 到上个操作指定的目录

cd /Users/psj/Desktop/t

#解压 tar 包

tar -xvf AccountBalance-0.0.1-SNAPSHOT.tar

#此时可查看目录结构如要求所示

ll

#运行 可执行jar，测试结果

java -jar AccountBalance-0.0.1-SNAPSHOT.jar

#

#打开浏览器，输入如下网址：

http://localhost:8101/accountbalance/swagger-ui.html

#

http://localhost:8999/accountsfile

#在下载对话框中指定文件名和保存路径

#

#打开新的iterm 窗口(command+n)

http localhost:8101/accountbalance/accounts

http localhost:8101/accountbalance/account/U00001

#返回上个 iterm 窗口，control+c 结束服务
