直接在你的拦截器里添加如下代码即可

//解决中文乱码问题  
    @Bean  
    public HttpMessageConverter<String> responseBodyConverter() \{  
        StringHttpMessageConverter converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));  
        return converter;  
    \}

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