springMVC配置运行报RequestMappingHandlerAdapter错误

springMVC.xml配置如下

 <?xml version="1.0" encoding="UTF-8"?>

    <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->

    <context:component-scan base-package="cn.sunky.controller" />
    <!--避免IE执行AJAX时,返回JSON出现下载文件 -->
    <!-- 定义跳转的文件的前后缀 ,视图模式配置-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- 配置文件上传,如果没有使用文件上传可以不用配置,当然如果不配,那么配置文件中也不必引入上传组件包 -->
    <bean id="multipartResolver"

        <!-- 内存中的最大值 -->

</beans>

报错信息如下:

现在可以锁定的是:不是少了jar包就是配置文件有问题。去看看你的配置文件。现在在加载xmlwebapplicationcontext的时候出错了。。

org.eclipse.yasson.JsonBindingProvider  没找到

问题解决了,是因为少了jar包导致的...
