Spring Mvc中@ResponseBody中文乱码解决汇总

spring 3 mvc 的 @ResponseBody返回数据用起来很方便,但是中文乱码,而且返回的Content-Type不带编码信息,网上有很多解决方法，但是大部分都存在一些问题，这里只介绍一种，如下：

自己写一个继承StringHttpMessageConverter的类UTF8StringHttpMessageConverter,内容参考 StringHttpMessageConverter.java中的代码，该类参考代码如下：

package com.aikang.common;

import java.io.IOException;
import java.io.OutputStreamWriter;
import java.nio.charset.Charset;
import java.util.Arrays;
import java.util.List;

import org.springframework.http.HttpOutputMessage;
import org.springframework.http.MediaType;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.util.FileCopyUtils;

public class UTF8StringHttpMessageConverter extends StringHttpMessageConverter {
private static final MediaType utf8 = new MediaType("text", "plain",
Charset.forName("UTF-8"));
private boolean writeAcceptCharset = true;

@Override
protected MediaType getDefaultContentType(String t) {
return utf8;
}

@Override
protected List<Charset> getAcceptedCharsets() {
return Arrays.asList(utf8.getCharSet());
}

@Override
protected void writeInternal(String s, HttpOutputMessage outputMessage)
throws IOException {
if (this.writeAcceptCharset) {
outputMessage.getHeaders().setAcceptCharset(getAcceptedCharsets());
}
Charset charset = utf8.getCharSet();
FileCopyUtils.copy(s, new OutputStreamWriter(outputMessage.getBody(),
charset));
}

public boolean isWriteAcceptCharset() {
return writeAcceptCharset;
}

public void setWriteAcceptCharset(boolean writeAcceptCharset) {
this.writeAcceptCharset = writeAcceptCharset;
}
}

spring-servlet的配置文件如下：

<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="com.aikang.common.UTF8StringHttpMessageConverter" />
</list>
</property>
</bean>

注：一定要放在扫描器之前
