参数异常：扩展JdbcUserDetailsManager时需要'dataSource'或'jdbcTemplate'。

javaspringspring-securitydatasource
11

我对Spring还比较陌生，目前在尝试扩展JdbcUserDetailsManager时遇到了异常问题，因为我需要除提供的功能外的其他功能。该类的签名如下，并带有默认构造函数。

@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);
            }
        });
    }
}

我自定义的接口长这样：

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

简单的自动装配：

@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>

然而，在启动我的应用程序时，我得到了下面的异常，所以显然我肯定错过了什么？有人能告诉我是什么吗？

编辑： 我在上面包含了整个PrimeUserDetailsManager的主体内容。这是dataSource的定义：

<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>
@Bozho：我以为dataSource是从JdbcUserDetailsManager继承而来的，但看起来我错了...所以我猜我只需要将它添加到PrimeUserDetailsManager中？ - Daniel
@mgamulin：整个CustomerUserDetailsManager在我的第一篇帖子中都有提供。 - Daniel
抱歉：<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> - Daniel
抱歉，我没有更新我的第一篇帖子的权限 :-/ - Daniel
创建名为'primeUserDetailsManager'的bean时出错。你能发布Spring中这个bean的定义吗？ - nicholas.hauschild

您有两个bean。其中一个在XML中定义。另一个被创建是因为您已经使用了@Repository注释来注释您的类。这是导致问题的那个，因为您没有给它关于连接所需的“'dataSource'或 'jdbcTemplate'”指令。请注意，在异常中，bean的名称是“primeUserDetailsManager”。这是小写的简单类名，这是通过使用注释进行组件扫描创建的默认bean名称。
啊，我对Spring的了解不足。看来我得再翻一下参考手册 :-) 干杯！ - Daniel

我创建了一个中间类JdbcDaoSupport，它是所有DAO类继承的超类，看起来像这样：

import javax.annotation.PostConstruct;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.support.JdbcDaoSupport;

public class MyJdbcDaoSupport extends JdbcDaoSupport {
    @Autowired private DataSource dataSource;
    @PostConstruct
    private void initialize() {
        setDataSource(dataSource);
    }
}

假设您有一个数据源bean，其ID为“dataSource”，如OP所示。
对于我来说，在Spring 4.x中有效，但早期版本也应该可以使用。

这个解决方案同样适用于Spring 5.0.8。MyDao类继承了JdbcDatoSupport并实现了一个接口。 - Andrea Girardi

我解决这个问题的唯一方法是在我的DAO中定义以下内容。

 private SimpleJdbcTemplate simpleJdbcTemplate;

    protected SimpleJdbcTemplate getSimpleJdbcTemplate() {
        return simpleJdbcTemplate;
    }

    @Autowired
    public void setDataSource(DataSource dataSource) {
        this.simpleJdbcTemplate = new SimpleJdbcTemplate(dataSource);
    }

看起来SimpleJdbcDaoSupport没有在其setDataSource方法上使用@Autowired注释。

这在Spring 2.5中也可以工作。

/**
 * Sets the parent class DataSource to the auto-wired data source.
 * 
 * 
 */
@Autowired
public void setParentDataSource(
        @Qualifier("dataSource") DataSource dataSource) {
    super.setDataSource(dataSource);
}
