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 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());
