本文介绍了一种常见错误，即在使用Spring MVC框架时，RestTemplate无法处理HTML响应的问题。该问题源于RestTemplate默认不支持HTML内容类型。文章提供了详细的解决方案，包括自定义HttpMessageConverter以支持text/html类型，并将其添加到RestTemplate的转换器列表中。

RestTemplate 不支持[text/html;charset=UTF-8]

解决方法

1.自定义HttpMessageConverter, 加入加入text/html类型的支持

public class MyMappingJackson2HttpMessageConverter extends MappingJackson2HttpMessageConverter {
    public MyMappingJackson2HttpMessageConverter(){
        List<MediaType> mediaTypes = new ArrayList<>();
        mediaTypes.add(MediaType.TEXT_PLAIN);
        mediaTypes.add(MediaType.TEXT_HTML);  //加入text/html类型的支持
        setSupportedMediaTypes(mediaTypes);
    }
}

2.将自定义的Converter加入restTemplate的messageConverters list中

RestTemplate rest= new RestTemplate(httpRequestFactory);
rest.getMessageConverters().add(new MyMappingJackson2HttpMessageConverter());
