【求助】跟着书本学习spring，遇到Injection of autowired dependencies failed，请求大佬帮忙看看

qq_36463974 2019-03-11 10:41:50
我是用IDEA创建的MAVEN项目，结构如下

然后在dao层
userDao
@Repository

public class UserDao {



    @Autowired

    private JdbcTemplate jdbcTemplate;





    public int getMatchCount(String userName, String password) {

        String sqlStr = " SELECT count(*) FROM t_user "

                + " WHERE user_name =? and password=? ";

        return jdbcTemplate.queryForInt(sqlStr, new Object[]{userName, password});

    }

LoginLogDao
@Repository

public class LoginLogDao {

    @Autowired

    private JdbcTemplate jdbcTemplate;



    public void insertLoginLog(LoginLog loginLog) {

        String sqlStr = "INSERT INTO t_login_log(user_id,ip,login_datetime) "

                + "VALUES(?,?,?)";

        Object[] args = {loginLog.getUserId(), loginLog.getIp(),

                loginLog.getLoginDate()};

        jdbcTemplate.update(sqlStr, args);

    }

service层UserService
@Service

public class UserService  {



    @Autowired

    private UserDao userDao;



    @Autowired

    private LoginLogDao loginLogDao;



    public boolean hasMatchUser(String userName, String password) {

        int matchCount = userDao.getMatchCount(userName, password);

        return matchCount > 0;

    }

public void loginSuccess(User user) {

        LoginLog loginLog = new LoginLog();

        loginLog.setUserId(user.getUserId());

        loginLog.setIp(user.getLastIp());

        loginLog.setLoginDate(user.getLastVisit());

        loginLogDao.insertLoginLog(loginLog);

    }

然后使用testng对userservice下的方法进行测试
UserServiceTest
@ContextConfiguration(locations = {"/applicationContext*.xml"})

public class UserServiceTest extends AbstractTestNGSpringContextTests {



    @Autowired

    private UserService userService;



    @Test

    public void hasMatchUser() {

        boolean b1 = userService.hasMatchUser("admin", "123456");

        boolean b2 = userService.hasMatchUser("admin", "1111");

        assertTrue(b1);

        assertTrue(!b2);

    }







    @Test

    public void loginSuccess() {

        User user = userService.findUserByUserName("admin");

        user.setUserId(1);

        user.setUserName("admin");

        user.setLastIp("192.168.12.7");

        user.setLastVisit(new Date());

        userService.loginSuccess(user);

    }

}

运行报错如下

spring默认是使用jdk动态代理，生成代理对象的，你这个service没有实现对应的接口，现在有两种方式解决: 1 抽取接口 让userserviceimpl实现接口userservice 将@service注解标注到userserviceimpl上，这样就能生成的对应的代理对象 2 强制使用cglb代理方式，使用实现类来生成代理对象。

当类的名字是以两个或以上的大写字母开头的话，bean的名字会与类名保持一致

报了这个错Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.
把cglib包加进去试一下
<!-- https://mvnrepository.com/artifact/cglib/cglib -->
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2</version>

配置用
@ContextConfiguration(locations = { "classpath*:applicationContext.xml" })

呼，总算解决了，感谢大神，原来是少包了[/quote]

看看22楼，是不是aop包没导入，aop包里应该包括了cglib库[/quote]
是的，用maven自动导包里头cglib一直失败

或者你可能没有导入spring-aop的依赖，加入试一下 <!-- https://mvnrepository.com/artifact/org.springframework/spring-aop --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>你的版本</version> </dependency>

有报错就好办了，依次改成下面的试一下
@ContextConfiguration(locations = { "classpath*:resources/applicationContext.xml" })
@ContextConfiguration(locations = { "classpath*:applicationContext.xml" })[/quote]
第一种报的是注入失败，第二种Failed to load ApplicationContext

引用 12 楼 鱼七 的回复:
注入bean失败
出现这个异常，就是找不到对应的 bean ，能够导致 bean 注入失败的原因包括以下几种但不限于这几种：
1.对应的 bean 没有添加注解；
2.对应的 bean 添加注解错误，例如将 Spring 的@Service错选成 dubbo 的；
3.选择错误的自动注入方法等。

或者是你调用的service的方法加上get试试

Spring 的@Service错选成 dubbo 的，能不能详细说说
