java.lang.IllegalArgumentException：警告此类型名称不匹配：UserDaoImpl [Xlint：invalidAbsoluteTypeName]

Question

我正在开发一个基于Spring 3.0.2的项目。从过去三天开始显示以下错误。

  

java.lang.IllegalArgumentException：警告此类型名称不匹配：UserDaoImpl [Xlint：invalidAbsoluteTypeName]

如何解决此错误？

userDaoImpl在UserController类中自动装配，该类使用@Controller进行注释：

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package web;

import dao.UserDaoImpl;
import domain.UsersTable;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;

/**
 *
 * @author amit
 */

@Controller
@RequestMapping("/userRegistration.htm")
@SessionAttributes("user")
public class UserController {

    @Autowired
    private UserDaoImpl userDaoImpl;

    public UserDaoImpl getUserDaoImpl() {
        return userDaoImpl;
    }

    public void setUserDaoImpl(UserDaoImpl userDaoImpl) {
        this.userDaoImpl = userDaoImpl;
    }   

    @RequestMapping(method = RequestMethod.GET)
    public String showForm(ModelMap model) {
        System.out.println("Get request found. . . . *****************************");
        UsersTable user = new UsersTable();
        model.addAttribute("user", user);
        return "registrationForm";
    }

    @RequestMapping(method = RequestMethod.POST)
    public ModelAndView OnSubmit(@ModelAttribute("user") UsersTable user) {
        System.out.println("User Object is : "+user);
        userDaoImpl.saveUser(user);
        return new ModelAndView("userConfirm", "user", user);
    }
}

Aspect Profiler：

package Profiler;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class AspectProfiler {
   @Pointcut("execution(* UserDaoImpl.mySave())")
            public void insertionProfiler(){ }

    @Around("insertionProfiler()")
            public void aroundInsertionProfiler(ProceedingJoinPoint pjp) throws Throwable{
            System.out.println("Before Insertion....");
            pjp.proceed();
            System.out.println("After saving the data I am back.");
    }

}

Answer 1

我不知道为什么今天我的RSS提要会出现这个旧问题，但仅仅是为了记录，正确的答案是在注释风格的AspectJ切入点中你需要使用完全限定的类名 < em>包括包名 ，即切入点应为

@Pointcut("execution(* dao.UserDaoImpl.mySave())")

这就是[Xlint:invalidAbsoluteTypeName]首先暗示的内容。

我想知道为什么在2011年没有其他人注意到这一点。

Answer 2

是注释之间的空格。和

中的类名

<bean class="org.springframework.web.servlet.mvc.annotation. DefaultAnnotationHandlerMapping" />

<bean class="org.springframework.web.servlet.mvc.annotation. AnnotationMethodHandlerAdapter" />

这里只有一个复制粘贴错误，或者它们是否真的在你的xml中？如果是，请将其删除并重试。

Answer 3

您的UserController已将 @Autowired 属性命名为UserDaoImpl。这是无效的，应该是userDaoImpl

Answer 4

            

你丢了“l”，应该是“userDaoImpl”。
