You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:
struts.devMode=false
in your WEB-INF/classes/struts.properties file.
上面就是报的异常信息：
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type
从上面的异常信息可以分析出：肯定出现在需要动态代理的地方。现在再来分析，Service和Dao单独测试都已经没有问题了，那么问题肯定出现在Action中了，配置文件对了一遍没问题，再去看下Action类，发现如下图：
解决方法就是：把Action中的Service的注入改一下，把实现类改为用接口接收。
/**
* Customer模块表现层Action类
*/
public class CustomerAction extends ActionSupport implements ModelDriven<Customer>{
/**
* Customer模块service层实现类实例对象，由Spring注入
*/
private ICustomerService customerService;
public void setCustomerService(ICustomerService customerService) {
this.customerService = customerService;
}
}
