springBoot自带的json用着不太习惯，已习惯了fastJSON，下面介绍下fastjson的配置
1. pom引入
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.15</version>
</dependency>
2.配置时间格式及编码，反正中文乱码
package com.xiao.config;import java.util.ArrayList;
import java.util.List;import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;@Configuration
public class FastJSONConfig extends WebMvcConfigurerAdapter {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
FastJsonConfig fastJsonConfig = new FastJsonConfig();
fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat);
fastJsonConfig.setDateFormat("yyyy-MM-dd HH:mm:ss");
// 处理中文乱码问题
List<MediaType> fastMediaTypes = new ArrayList<>();
fastMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
fastConverter.setSupportedMediaTypes(fastMediaTypes);
fastConverter.setFastJsonConfig(fastJsonConfig);
converters.add(fastConverter);
}
}
3.代码测试
@RequestMapping(value = "/json/test")
public Result jsonTest(@Valid User user) {
System.out.println(JSON.toJSONString(user));
return new Result(user);
}
4.结果
