springboot响应消息（http）的编码设置

一、方式一

在单个REST接口上设置

    @ResponseBody
    @RequestMapping(value = "sys/getTree1",method = RequestMethod.POST,produces="application/json;charset=UTF-8")
    public String getTree1(){
        return "success";
    }

二、方式二

全局配置（推荐）

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

    @Override
    protected void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(responseBodyConverter());
        super.configureMessageConverters(converters);
    }
    @Bean
    public HttpMessageConverter responseBodyConverter() {
        StringHttpMessageConverter converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
        return converter;
    }
}
