Spring NoSuchMethodException（我创建了一个构造函数）

时间：2016-01-18 04:06:35

标签： java spring hibernate spring-mvc

我想问一下我在哪里出错了。我刚刚使用Spring和Hibernate 4启动了一个简单的登录功能，但似乎我似乎总是得到NoSuchMethodException。试着到处查看我出错的地方，但这就像我从来没有做到这一点。任何帮助将非常感谢。以下是代码。

非常感谢帮助。非常感谢你！

不确定我是否已经回答了问题。

这是我的测试

package com.services.impl;

import static org.junit.Assert.assertEquals;

import java.util.List;

import javax.transaction.Transactional;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.model.User;
import com.model.UserDAO;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext-test.xml")
public class StudyPointRepositoryTest {

    @Autowired
    private UserServiceImpl userService;

    @Autowired
    private UserDAO dao;

    @Test
    @Transactional
    public void test1() {

        dao.save(makeUser("Fred", "pass1"));
        dao.save(makeUser("Bill", "pass2"));
        dao.save(makeUser("Nobby", "pass3"));

        List<User> validate = userService.validate("Fred", "pass1");
        assertEquals(1, validate.size());

        validate = userService.validate("Fred", "wrongpass");
        assertEquals(0, validate.size());
    }

    private User makeUser(String name, String password) {
        User user = new User();
        user.setName(name);
        user.setPassword(password);
        return user;
    }

}

这是我的测试配置

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

</beans>

这是我的DAO

package com.model; 

import java.util.List;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface UserDAO extends CrudRepository<User, Integer> {

    List<User> findByNameAndPassword(String name, String password);
}

这是我的服务

package com.services.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.model.User;
import com.model.UserDAO;

@Service
public class UserServiceImpl {

    @Autowired
    private UserDAO userDAO;

    public List<User> validate(String name, String password) {
        return userDAO.findByNameAndPassword(name, password);
    }

}

这是我的pom，可能的东西，不需要
