6 Spring MVC 学习笔记九 json格式的输入和输出
http://starscream.iteye.com/blog/1067606

在SpringMVC中使用JSON必须注意二点
1 必须包含:jackson的jar包,我使用的是: jackson-all-1.8.1.jar,
可在官网:http://mvnrepository.com/artifact/org.codehaus.jackson中去下载
2 在springmvc.xml配置文件中必配置: <mvc:annotation-driven/>
3 jquery.json-*.*.min.js
实现功能: 从后台获取对象,List,Map在前台显示,前台提交JSON数据格式到后台并且返回

都写了<mvc:annotation-driven/> ，又写了AnnotationMethodHandlerAdapter，这样有没有关系？

                            for(var i=0;i<leng;i++){  
                              info += data[i].id + "," + data[i].name + "," + data[i].sex + "," + data[i].password + "," + data[i].address + "," + data[i].age+"<br>";  
                            }                                                                             
                            $("#listInfo").html(info);  */  
                              
                            var info = '';    
                             $.each(data,function(index,entity) {   
                               info += "姓名: " + entity.name+",年龄: " + entity.age + ",地址: " + entity.address + ",性别: " + (entity.sex == 1 ? "男" : "女")+",密码: " + entity.password+"<br>";     
                             });  
                             $("#listInfo").html(info);  
                                
                                                                         
                    });  
     });

这个可不可以用

<c:forEach items="${listInfo}" var="list">
<tr>
<td>${list.name}</td>
<td>${list.age}</td>
<td>${list.sex}</td>
<td>${list.password}</td>
<td>${list.address}</td>
</tr>
</c:forEach>

代替呢?

你好，我想请问下我请求的时候一直报406错误是什么情况（Firebug检测的），然后我把你的程序下载下来运行也是一样的，都报这错误，已经成功请求服务端，只是在返回数据的时候出的问题。请问知道这是什么情况吗？

谢了，想找一个完整的大型的项目学习一下

用到springmvc+jquery，就会遇到JSON的问题，jquery1.3.2可以把数组从jsp传入到controller去，但是后面的版本就不行了，至今1.7的版本还是不能传入复杂数据。请问楼上的大侠有没有好的解决办法呢？

8 楼 helloguoxing 2012-05-31

已经解决了，多谢楼上的大侠！

7 楼 liuzidong 2012-04-16

从二方面查找下原因吧！

1 确保jQuery前台调用没问题，用FF查看
2 后台.do的配置是否正确，可从请求方法打印日志查看下

我按照上面的配置后，结果ajax返回没有反映，请问大侠遇到过该问题吗？

liuzidong 写道

用了org.springframework.web.filter.CharacterEncodingFilter一般就没有乱码的问题了，你试过吗，请提意见呀

为何注释掉下面这段代码呢？

 <!-- 
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean
					class="org.springframework.http.converter.StringHttpMessageConverter">
					<property name="supportedMediaTypes">
						<list>
							<value>text/html;charset=UTF-8</value>
						</list>
					</property>
				</bean>
			</list>
		</property>
	</bean>
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
	-->

jquery跟spring mvc交互有点复杂了，提交数据还要先进行序列化。。。

2 楼 source78 2011-08-13

貌似没考虑返回乱码问题

1 楼 guyuelong2010 2011-07-07

谢啦，先研究一下，好好看看啊
