在某些请求期间没有发生自动装配

Autowiring not happening during certain request

我是 spring-security.I 的新手,对 @Autowired 注释有疑问。

下面是我的spring-security.xml文件:

<http pattern="/login" security="none" />
<http pattern="/signup" security="none" />
<http pattern="/views/**" security="none" />
<http pattern="/createUser" security="none" />
<http pattern="/practice" security="none" />
<http use-expressions="true" authentication-manager-ref="authenticationManager">
    <intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
    <form-login login-page="/login" default-target-url="/home"
        authentication-failure-url="/login" username-parameter="username"
        password-parameter="password" login-processing-url="/j_spring_security_check" />
    <logout logout-success-url="/login" invalidate-session="true"
        logout-url="/j_spring_security_logout" delete-cookies="JSESSIONID" />
    <session-management invalid-session-url="/login">
        <concurrency-control max-sessions="1"
            expired-url="/login" />
    </session-management>
</http>
<authentication-manager id="authenticationManager">
    <authentication-provider user-service-ref="userDetailsService" />
</authentication-manager>
<beans:bean id="userDetailsService" class="com.practice.service.UserDetailsServiceImpl" />

<beans:bean name="
    passwordEncoder "
    class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" />

这是我的spring-servlet.xml配置:

<context:annotation-config/>
<context:component-scan base-package="com.practice" />
<mvc:resources mapping="/views/**" location="/views/" />
<mvc:annotation-driven />

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations"
        value="classpath:com/practice/resources/database.properties"></property>
</bean>

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

<bean id="dataSource" destroy-method="close"
    class="org.apache.commons.dbcp.BasicDataSource">
    <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>

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation">
        <value>classpath:com/practice/resources/hibernate.cfg.xml</value>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
        </props>
    </property>
</bean>

<tx:annotation-driven />

<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean> 

我会请求注册页面,在填写必要的详细信息后,它会到达我的控制器,我将用户保存在数据库中,然后我根据我存储在数据库。我按照这个 Whosebug post 寻求指导。

奇怪的是 class 中没有自动装配,我在其中实现了 UserDetailsS​​ervice 接口:

@Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService {

@Autowired
PasswordEncoder passwordEncoder;

@Autowired
UserService userService;

@Override
public UserDetails loadUserByUsername(String arg0)
        throws UsernameNotFoundException {
    System.out.println("ddfddd");
    return null;
}}

而自动装配正在其他服务 classes 中进行,我在那里自动装配了与上述相同的字段!

同样的事情发生在我登录时,当我调试时,字段为空!并且在 classes 中我写了我的 CustomAuthenticationProvider !

有什么建议吗??如果我的配置有任何错误请指正。

更新

我收到以下错误,

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.practice.service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

当我删除 @Service 注释和添加 context:annotation-config

如果您定义了一个带有 @Component 注释的 UserService bean,它被 spring-servlet.xml 中的组件扫描拾取,那么问题可能是 spring-servlet.xml 是来自 spring-security.xml 的子应用程序上下文。在那种情况下,安全上下文中的 bean 无法访问子上下文中的任何 bean,只能反过来访问。因此,您必须确保所有必需的 bean 都可以从 spring-security.xml 上下文访问(例如,通过显式指定所有 bean 或通过移动 [= 中的 annotation-config 和 component-scan 元素17=]-security.xml 上下文)。
