搭建dubbo工程时，Service层无法注入mapper问题

测试service 时，无法注入mapper

在dao工程中 测试mapper OK 将同样的测试代码放到service工程 ，发现无法注入 mapper

import entity.Users; import mapper.UserMapper; 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; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath:spring/spring-*.xml"}) public class TestUserMapper { @Autowired private UserMapper userMapper; @Test public void register(){ Users users = new Users(); users.setPhone("123456"); users.setCreatetime("123"); users.setPassword("123"); users.setUsername("张飞"); userMapper.register(users); } } ``
