如何解决java.lang.IllegalArgumentException：警告与此类型名称不匹配：UserDaoImpl [Xlint：invalidAbsoluteTypeName]

| 我正在开发一个基于Spring 3.0.2的项目。从最近三天开始，它显示以下错误。 java.lang.IllegalArgumentException：警告与此类型名称不匹配：UserDaoImpl [Xlint：invalidAbsoluteTypeName] 我该如何解决这个错误？我的applicationContext文件是：

userDaoImpl在与@Controller一起注释的UserController类中是自动装配的：

/*
 * 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.\");
    }

}

解决方法

我不知道为什么这个老问题今天在我的RSS feed上突然出现，但是仅作记录，正确的答案是在注释样式的AspectJ切入点中，您需要使用完全合格的类名称，包括程序包名称，即切入点应该是

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

这就是“ 5”最初的含义。我想知道为什么在2011年没有人注意到这一点。 , 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\" />

这里只是复制粘贴错误，还是它们确实在您的xml中？如果是这样，则将其删除，然后重试。 , 您的UserController具有@Autowired属性，名为UserDaoImpl。这是无效的，应该是userDaoImpl , 您丢失了“ l”，应该是“ userDaoImpl \”。
