org.springframework.beans.NotWritablePropertyException: Invalid property ''regis

org.springframework.beans.NotWritablePropertyException: Invalid property ''registerDAO'' of bean class [service.RegisterService]: Bean property ''registerDAO'' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
原因：
在service中，registerDAO没有set方法。注意set方法的名字，一定要和属性保持一致
如：
private SelfAppointDAO selfAppointDAO;
// 错误的set方法
public void setAppointDAO(SelfAppointDAO myAppointDAO) {
this.selfAppointDAO = myAppointDAO;
}
//正确的set方法
public void setSelfAppointDAO(SelfAppointDAO myAppointDAO) {
this.selfAppointDAO = myAppointDAO;
}

我也抛砖引玉吧

struts2 出现这样的异常
Could not find action or result No result defined for action com.xx.action.xxAction and result input

是因为Action属性为空时默认拦截器报错,同时会找名为:input 的result. 所以有可能是jsp页面中某个属性为空或者类型不匹配造成的.而看错误信息很可能第一反应是xml配置有问题
