如何在JUnit测试中自动连接服务

Question

2014-12-20 15:35:52错误TestContextManager：334-允许TestExecutionListener[org.springframework.test.context.support.dependencyInjectionTestExecutionListener@5af97850]准备测试实例[com.amsb.bariz.base.test.usertest@4520ebad]org.springframework.beans.factory.beanCreationException：创建名为“com.amsb.bariz.base.test.usertest”的bean时发生异常：注入autowired依赖项失败；嵌套异常为org.springframework.beans.factory.beanCreationException：无法自动连接字段：public com.amsb.bariz.base.service.userservice com.amsb.bariz.base.test.usertest.userservice；嵌套异常为org.springframework.beans.factory.noSuchBeanDefinitionException：未找到依赖项得[com.amsb.bariz.base.service.userservice]类型得合格bean：需要至少一个具有此依赖项自动候选资格得bean.依赖项注释：{@org.SpringFramework.Beans.Factory.Annotation.AutoWired(required=true)}

我的服务类别是

package com.amsb.bariz.base.service.imp;

import java.sql.Timestamp;
import java.util.Calendar;
import java.util.Date;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import com.amsb.bariz.base.dao.UserDao;
import com.amsb.bariz.base.dao.UserRoleDao;
import com.amsb.bariz.base.entity.User;
import com.amsb.bariz.base.entity.UserRole;
import com.amsb.bariz.base.service.UserService;


@Service("userService")
public class UserServiceImp implements UserService {

    @Autowired
    private UserDao userDao;

    @Autowired
    private UserRoleDao userRoleDao;

    public void register(User user) {

        PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();

        user.setPassword(passwordEncoder.encode(user.getPassword()));
        Calendar calendar = Calendar.getInstance();
        java.util.Date now = calendar.getTime();

        Date dateNow = new Date(20070266);
        Timestamp dn = new Timestamp(now.getTime());
        user.setStatus("P");
        user.setCreated_on(dn);
        user.setEnabled(false);

        UserRole ur = new UserRole(user,"USER_ROLE");


        System.out.println("XDXDX ::" + user.toString());
        userDao.create(user);
        userRoleDao.create(ur);

    }

}

我的测试类是：

        Timestamp doo = new Timestamp(now.getTime());



        Date a = new Date(0);


        user.setPassword("oman");
        user.setName("oman new ");
        user.setStatus("N");
        user.setCreated_on(doo);
        user.setUpdated_on(doo);
        user.setDob(new Date(20140522));
        user.setUsername("[e-mail]");


        userService.register(user);
    }

Answer 1

您是否试图将测试本身作为Spring配置的一部分？那是行不通的。您需要做的是：-从测试本身中删除@configuration和@componentscan批注-创建一个简单的TestConfiguration类：

@Configuration
@ComponentScan(basePackages={"com.amsb.bariz.base.service"})
@ImportResource("classpath:spring/spring-main.xml")
public class TestConfiguration{ }

并在测试中引用它：

@ContextConfiguration(classes = { TestConfiguration.class }, loader = AnnotationConfigContextLoader.class)
public class UserTest {

你应该可以很好地注入你的服务。
