spring mvc在3.0中引入了responsebody这个注解,但是在源码中StringHttpMessageConverter 将默认编码写成了ISO-8859-1,并且是static final的,从网上搜了一堆,通过配置注入来解决,但是都是3.1的解决办法;看来只能通过重写+注入解决了,果然在网上搜到了一个贴了,试了下,可行~ 以下是帖子的一段~
@ResponseBody默认采取
public static final Charset DEFAULT_CHARSET = Charset.forName("ISO-8859-1");
的方式,我要修改为UTF-8,所以,就直接copy了源码,但是修改了一下里边的默认编码
import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.io.UnsupportedEncodingException;import java.nio.charset.Charset;import java.util.ArrayList;import java.util.List;import org.springframework.http.HttpInputMessage;import org.springframework.http.HttpOutputMessage;import org.springframework.http.MediaType;import org.springframework.http.converter.AbstractHttpMessageConverter;import org.springframework.util.FileCopyUtils;/** * @Author : wangxl * @Date : 2013-1-17 */public class UTF8StringHttpMessageConverter extends AbstractHttpMessageConverter{ public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); private final List availableCharsets; private boolean writeAcceptCharset = true; public UTF8StringHttpMessageConverter() { super(new MediaType[] { new MediaType("text", "plain", UTF8StringHttpMessageConverter.DEFAULT_CHARSET), MediaType.ALL }); this.availableCharsets = new ArrayList (Charset.availableCharsets() .values()); } public void setWriteAcceptCharset(boolean writeAcceptCharset) { this.writeAcceptCharset = writeAcceptCharset; } public boolean supports(Class clazz) { return String.class.equals(clazz); } @SuppressWarnings("rawtypes") protected String readInternal(Class clazz, HttpInputMessage inputMessage) throws IOException { Charset charset = getContentTypeCharset(inputMessage.getHeaders() .getContentType()); return FileCopyUtils.copyToString(new InputStreamReader(inputMessage.getBody(), charset)); } protected Long getContentLength(String s, MediaType contentType) { Charset charset = getContentTypeCharset(contentType); try { return Long.valueOf(s.getBytes(charset.name()).length); } catch (UnsupportedEncodingException ex) { throw new InternalError(ex.getMessage()); } } protected void writeInternal(String s, HttpOutputMessage outputMessage) throws IOException { if (this.writeAcceptCharset) { outputMessage.getHeaders().setAcceptCharset(getAcceptedCharsets()); } Charset charset = getContentTypeCharset(outputMessage.getHeaders() .getContentType()); FileCopyUtils.copy(s, new OutputStreamWriter( outputMessage.getBody(), charset)); } protected List getAcceptedCharsets() { return this.availableCharsets; } private Charset getContentTypeCharset(MediaType contentType) { if ((contentType != null) && (contentType.getCharSet() != null)) { return contentType.getCharSet(); } return DEFAULT_CHARSET; }}
然后,修改spring的注入配置,将自己编写的类注入到org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter中,配置代码如下
