springboot @RestController 返回中文亂碼

1、在具體的方法上指定返回編碼

@RequestMapping(value = "index", produces = "text/html;charset=utf-8")

 

2  、WebMvcConfigurer統一配置

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

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(responseBodyConverter());
    }
