问题：springboot项目本地没问题，部署linux服务器上，出现后台返回数据中文乱码问题，解决办法

1：第一种解决办法： 

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {

    @Bean
    public HttpMessageConverter<String> responseBodyConverter(){
        StringHttpMessageConverter converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
        return converter;
    }


    @Override
    protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        super.configureMessageConverters(converters);

        converters.add(responseBodyConverter());
    }
}

2：第二种解决办法

在RequestMapping里设置 produces = { “application/json;charset=UTF-8” }：

3：设置全局utf-8

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

4: 网上说这种方法，试了，没用  tomcat8以后默认编码UTF-8

<Connector port="00000" protocol="HTTP/1.1" URIEncoding="UTF-8"
			   useBodyEncodingForURI="true"
               connectionTimeout="20000"
               redirectPort="8443" />
