我有一个Web应用程序在部署时失败。我收到以下错误：

我使用

在 web.xml 中加载我的配置XML 
<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            WEB-INF/spring/spring-security.xml
            WEB-INF/spring/applicationContext-db.xml
            WEB-INF/spring/applicationContext.xml
        </param-value>
    </context-param>

错误来自我的 spring-security.xml 文件，其中包含：

<security:http auto-config="true" use-expressions="true"
        access-denied-page="/auth/denied">
        <security:intercept-url pattern="/auth/login"

        <security:intercept-url pattern="/main/admin"
            access="hasRole('ROLE_ADMIN')" />
        <security:intercept-url pattern="/main/common"

    </bean>
    <bean id="ldapContact" class="com.abc.xyz.ldapservices.LDAPUtil">
        <property name="ldapTemplate" ref="ldapTemplate" />
    </bean>

我的 CustomLoginSuccessHandler 类就像：

public class CustomLoginSuccessHandler implements AuthenticationSuccessHandler {


    /** The redirect strategy. */
    private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

    /** The ldap contact. */
    @Autowired
    LDAPUtil ldapContact;

我是Spring的新手，但我想这是由于bean依赖关系的配置。

1。它使用的是spring bean依赖的序列是什么     web.xml中的XML配置序列？
 假设我引用了bean A.     在XML文件中，它将在下面定义它所引用的位置     创造任何问题？

修改

我的LDAPUtil类就像：

private LdapOperations ldapTemplate;

public void setLdapTemplate(LdapTemplate ldapTemplate) {
            this.ldapTemplate = ldapTemplate;
}

1 个答案:

答案 0 :(得分：8)

错误提供了有用的元素。原因（链中的最后一个错误）是（剥离字符串）：

  

使用名称＆＃39; ldapContact＆＃39;创建bean时出错...无法转换类型＆$ 39; $ Proxy213实现的属性值... LdapOperations ...＆＃39;要求的类型＆＃39; .... LdapTemplate＆＃39;对于财产＆ldapTemplate＆＃39;

您没有显示LdapUtil来源，但是来自CustomSuccessHandler并且错误，我认为它包含在某处：

@Autowired
LdapTemplate ldapTemplate;

错误表明ldapTemplate bean周围存在AOP代理机制。

这不是问题，除了默认情况下Spring AOP使用JDK代理，代理实现所有接口，但不扩展原始类。您应该能够通过接口引用ldapTemplate来修复错误：

@Autowired
LdapOperations ldapTemplate;

或者，您可以要求Spring使用cglib代理，它通过在xml文件中使用<aop:config proxy-target-class = "true">来扩展原始类（如果使用注释，则使用<aop:aspectj-autoproxy proxy-target-class="true"/>）。但是这需要cglib jar在路径上，并且因为你可以使用接口，我建议你使用第一个解决方案。

编辑：

您修改过的帖子会显示您在ldapTemplate中加载LdapUtil的方式。当你应该以这样的方式使用接口时，你将它作为一个类加载：

private LdapOperations ldapTemplate;

public void setLdapTemplate(LdapOperations ldapTemplate) {
            this.ldapTemplate = ldapTemplate;
}
