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;
}
