SpringBoot 中文乱码

先添加fastjson依赖包，在重写方法 configureMessageConverters(List<HttpMessageConverter<?>> converters)

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.47</version>
        </dependency>

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {
    /* 解决中文乱码 RestController */
    @SuppressWarnings("serial")
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        // for string
        // 普通输出中文 使用utf-8
        converters.add(new StringHttpMessageConverter(Charset.forName("utf-8")));
        // for json
        // 普通输出中文 使用utf-8
        FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
        fastConverter.setSupportedMediaTypes(new ArrayList<MediaType>() {
            {
                add(MediaType.APPLICATION_JSON_UTF8);
            }
        });
        // 支持 输出 数组 对象 结果格式化美化 额外 输出 屏蔽 null值
        FastJsonConfig fastJsonConfig = new FastJsonConfig();
        fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat, SerializerFeature.WriteNullListAsEmpty,
                SerializerFeature.WriteNullStringAsEmpty);
        fastConverter.setFastJsonConfig(fastJsonConfig);

        converters.add(fastConverter);
    }

}

SpringMVC 中文乱码

解决中文乱码response
response.setContentType(“text/html;charset=UTF-8”);
(HandlerInterceptor preHandle 定义拦截器这样无需每次手段设置)
response.getWriter()
解决中文乱码ResponseBody
@RestController @ResponseBody
// produces = “application/json; charset=utf-8”
（xml配置，这样无需每次手动设置）
< mvc:annotation-driven >
< !– 消息转换器 –>

< bean class=”org.springframework.http.converter.StringHttpMessageConverter”>
< property name=”supportedMediaTypes” value=”text/html;charset=UTF-8”/>
