Spring MVC响应编码问题 [英] Spring MVC response encoding issue

问题描述

在过去几个小时，我已经阅读了很多关于这个主题，到目前为止没有什么工作。我试图返回包含奇怪一些字符的响应。下面是一个很简单的例子：

  @ResponseBody 
 @RequestMapping（value =test）
 public String test（）{
 String test =čćžđš; 
 System.out.println（test）; 
 logger.info（test）; 
 return test; 
} 
  

这是我的

我认为正确的方法是返回UTF-8，也许我错了。

解决方案

几天后，我只有谁是你的爸爸时刻。它来自阅读spring 3.0参考，我没有什么别的可以尝试，所以为什么不走槽整个文档..和组合@axtavt答案：

在Spring MVC中设置响应内容类型（@ResponseBody）

更改原始解决方案：

  public class EncodingPostProcessor实现BeanPostProcessor {
 public Object postProcessBeforeInitialization（Object bean，String name）
 throws BeansException {
 if（Bean instanceof AnnotationMethodHandlerAdapter）{
 HttpMessageConverter<？> [] convs =（（AnnotationMethodHandlerAdapter） bean）.getMessageConverters（）; 
 for（HttpMessageConverter<？> conv：convs）{
 if（conv instanceof StringHttpMessageConverter）{
（（StringHttpMessageConverter）conv）.setSupportedMediaTypes（
 Arrays.asList （text，html，
 Charset.forName（UTF-8）））））; 
} 
} 
} 
 return bean; 
} 
  

To：

  public class EncodingPostProcessor implements BeanPostProcessor {
 public Object postProcessBeforeInitialization（Object bean，String name）
 throws BeansException {
 if（Bean instanceof AnnotationMethodHandlerAdapter）{
 HttpMessageConverter<？> [] convs =（（AnnotationMethodHandlerAdapter）bean）.getMessageConverters（）; 
 for（HttpMessageConverter<？> conv：convs）{
 if（conv instanceof StringHttpMessageConverter）{
（（StringHttpMessageConverter）conv）.setSupportedMediaTypes（
 Arrays.asList （text，plain，
 Charset.forName（UTF-8）））））; 
} 
} 
} 
 return bean; 
} 
  

但仍然会继续使用它。

In last few hours I've read a lot concerning this topic, and so far nothing has worked. I'm trying to return response containing "odd" some characters. Here is example of that, quite simple :

@ResponseBody
    @RequestMapping(value="test")
    public String test(){
        String test = "čćžđš";
        System.out.println(test);
        logger.info(test);
        return test;
    }

This is my web.xml, because I found some answers where CharacterEncodingFilter helped(not in my case though). I used POST method because I read this applies to POST.

Also found this answer(related). Didn't help as well.

When I debug it the correct value appears, but when I print it doesn't as it can be seen below:

When I test it from jmeter, the response seems to be OK, Content-Type is text/html;charset=UTF-8

Here is a screenshot of that as well. http://i56.tinypic.com/14lt653.jpg

I think the right way is to return UTF-8, maybe I'm wrong.

解决方案

After few days of this I just had "who's your daddy moment". It came from reading spring 3.0 reference, I had nothing else to try so why not go trough entire documentation.. and combination of @axtavt answer :

Who sets response content-type in Spring MVC (@ResponseBody)

Changed original solution :

public class EncodingPostProcessor implements BeanPostProcessor {
    public Object postProcessBeforeInitialization(Object bean, String name)
            throws BeansException {
        if (bean instanceof AnnotationMethodHandlerAdapter) {
            HttpMessageConverter<?>[] convs = ((AnnotationMethodHandlerAdapter) bean).getMessageConverters();
            for (HttpMessageConverter<?> conv: convs) {
                if (conv instanceof StringHttpMessageConverter) {
                    ((StringHttpMessageConverter) conv).setSupportedMediaTypes(
                        Arrays.asList(new MediaType("text", "html", 
                            Charset.forName("UTF-8"))));
                }
            }
        }
        return bean;
    }

To :

public class EncodingPostProcessor implements BeanPostProcessor {
    public Object postProcessBeforeInitialization(Object bean, String name)
            throws BeansException {
        if (bean instanceof AnnotationMethodHandlerAdapter) {
            HttpMessageConverter<?>[] convs = ((AnnotationMethodHandlerAdapter) bean).getMessageConverters();
            for (HttpMessageConverter<?> conv: convs) {
                if (conv instanceof StringHttpMessageConverter) {
                    ((StringHttpMessageConverter) conv).setSupportedMediaTypes(
                        Arrays.asList(new MediaType("text", "plain", 
                            Charset.forName("UTF-8"))));
                }
            }
        }
        return bean;
    }

Darn spring!!! but still I'll continue to use it.
