今天使用spring返回json形式,需要配置jsckson包使用,我用的是jackson-all-1.8.1.jar。
springMVC-servlet.xml中也配置了<mvc:annotation-driven/>,也对包进行了扫描!
但是启动的时候就是报错,希望大家给我看一下。
网上有说myeclipse自动加的spring框架的话,里面有包的版本的冲突,我已经将那低版本的都删掉了。最后偶还是不行,很着急。。。

类型转换失败,在spring容器中获取的对象在转换时失败,有个bean不能实例化
仔细检查你的spring容器中的bean和对应类的关系。有可能注入的类型不匹配。
<!--ajaxjson--><!--json--><beanclass="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><propertyname="messageConverters"><list><refbean="mappingJacksonHttpMessageConverter"/></list></property></bean><beanid="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> 上面的配置有吗?网上不是说配置了<mvc:annotation-driven/>就不用配置那几个bean么?我当时也试了也配上了这几个bean,但是依旧不行。。。Servlet/JDBC-SpringMVC-Springthrewload()exception |
应该是2代的吧,忘了是从哪个版本开始的了
你的spring和jackson版本是多少?我用的spring3.2.6,jackson2.2,对应的converter是2代的
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"回复 @路飞:好吧。。。。3Q回复 @赵运达:最早到3.1.2版本支持jackson2.x,1.x的支持版本暂时没找到(http://stackoverflow.com/questions/10420040/jackson-2-0-with-spring-3-1)话说,你为什么不升级下spring和jackson呢-_-!!!我是spring3.0~~~~应该对应什么样的呢 org.codehau100%这个包冲突。可能存在多个版本该jar包。回复 @赵运达:删掉一个。。怎么解决呢?
org.codehaus.jackson.type.JavaType
就是这个类冲突啊,你看下两个包里面是不是都有。
只留一个,另一个要删掉。
你说的那个类在jackson包里面有,但是spring的没有啊。。。spring的是org.codehaus.jackson.map.type现在解决了吗,我今天遇到这个问题,不知其解
