百度,iteye上面一搜索,一大推文章,但是按照类似的配置,都不起作用,按照一些文章的写法,继承了StringHttpMessageConverter 也无法解决问题,无奈之下,翻了翻源码,重新写个一个关于@ResponseBody的内容编码,解决。
@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<String> { public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); private final List<Charset> availableCharsets; private boolean writeAcceptCharset = true; public UTF8StringHttpMessageConverter() { super(new MediaType[] { new MediaType("text", "plain", UTF8StringHttpMessageConverter.DEFAULT_CHARSET), MediaType.ALL }); this.availableCharsets = new ArrayList<Charset>(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<Charset> 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
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <bean id="utf8StringHttpMessageConverter" class="**.UTF8StringHttpMessageConverter" /> </list> </property> </bean>
终于接受到了中文,谢天谢地~搞了一上午加2个小时
PS:配置写在spring扫描servlet之前
