java - IllegalArgumentException : 'dataSource' or 'jdbcTemplate' is required when extending JdbcUserDetailsManager

Question

我对 Spring 还是很陌生，目前我正在努力解决在尝试扩展 JdbcUserDetailsManager 时引发的异常，因为除了提供的功能之外，我还需要其他功能。类签名看起来像这样，带有一个默认构造函数。

@Repository
public class PrimeUserDetailsManager extends JdbcUserDetailsManager implements CustomUserDetailsManager {

    public static String CUSTOM_USERS_BY_USERNAME_QUERY = "select username,password,enabled from users where username like ?%";  
    public static String FIND_ALL_USERS_QUERY = "select username,password,enabled from users";

    @Override
    public List<UserDetails> loadUsersByUsername(String username) {
        return super.loadUsersByUsername(username);
    }

    @Override
    public List<UserDetails> findAllUsers() {
        return getJdbcTemplate().query(FIND_ALL_USERS_QUERY, new RowMapper<UserDetails>() {
            public UserDetails mapRow(ResultSet rs, int rowNum) throws SQLException {
                String username = rs.getString(1);
                String password = rs.getString(2);
                boolean enabled = rs.getBoolean(3);
                return new User(username, password, enabled, true, true, true, AuthorityUtils.NO_AUTHORITIES);
            }
        });
    }
}

}

我的自定义界面如下所示:

public interface CustomUserDetailsManager extends UserDetailsManager {
    public List<UserDetails> loadUsersByUsername(String username);
    public List<UserDetails> findAllUsers();
}

简单的 Autowiring :

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

    @Autowired
    public UserServiceImpl(CustomUserDetailsManager customUserDetailsManager) {
        this.customUserDetailsManager = customUserDetailsManager;
    }

    private CustomUserDetailsManager customUserDetailsManager;
    ....
}

在我的 ApplicationContext 中，我有这个:

<beans:bean id="jdbcUserService" class="org.primefaces.examples.moviecollector.custom.PrimeUserDetailsManager">
    <beans:property name="dataSource" ref="dataSource"/>
    <beans:property name="authenticationManager" ref="authenticationManager"/>
    <beans:property name="enableGroups" value="true"/>
    <beans:property name="enableAuthorities" value="false"/>
</beans:bean>

不过，当我盯着我的应用程序时，我得到了下面的异常，所以显然我一定错过了什么？有人可以告诉我什么吗？

编辑:我已经包含了上面 PrimeUserDetailsManager 的整个主体。这是数据源定义:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >
    <property name="driverClassName" value="${database.driver}"/>
    <property name="url" value="${database.url}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>
</bean>

你有两个 bean 。一种是在 XML 中定义的。因为你已经用 @Repository 注释了你的类，所以正在创建另一个。这就是给你带来麻烦的一个，因为你没有给它任何关于连接所需的“'dataSource'或'jdbcTemplate'”的说明。请注意，bean 的名称为“primeUserDetailsManager”。这是小写的简单类名，是bean的默认名称created via component scanning with annotations .
