解决spring mvc rest 中文乱码

contorller.xml配置

 

<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean id="utf8StringHttpMessageConverter"
					class="cn.com.xxx.util.UTF8StringHttpMessageConverter" />
			</list>
		</property>
	</bean>

 

 转换类要继承org.springframework.http.converter.StringHttpMessageConverter

 

 

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