無法在UserDetailsS​​ervice中自動裝載DAO類

Question

標題說明了一切。

這裏是我的應用程序的安全性-context.xml的

<?xml version="1.0" encoding="UTF-8"?> 
<beans:beans xmlns="http://www.springframework.org/schema/security" 
    xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:util="http://www.springframework.org/schema/util" xmlns:jee="http://www.springframework.org/schema/jee" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
         http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd 
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd 
         http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd 
     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"> 

    <global-method-security pre-post-annotations="enabled" /> 

    <http auto-config="true" use-expressions="true"> 

     <intercept-url pattern="/login" access="permitAll" /> 
     <intercept-url pattern="/show" access="hasRole('ROLE_USER')" /> 
     <intercept-url pattern="/action" access="hasRole('ROLE_USER')" /> 

     <form-login 
      login-page="/login" 
      default-target-url="/show" 
      always-use-default-target="true" 
      authentication-failure-url="/login?error" 
      username-parameter="username" 
      password-parameter="password" 
     /> 

     <logout logout-success-url="/login?logout" />  

    </http> 

    <!-- <authentication-manager> 
     <authentication-provider> 
      <user-service> 
       <user name="jimi" password="jimi" 
        authorities="ROLE_USER" /> 
      </user-service> 
     </authentication-provider> 
    </authentication-manager> --> 

    <context:component-scan base-package="com.security" /> 
    <context:component-scan base-package="com.dao" /> 

    <authentication-manager> 
    <authentication-provider user-service-ref="user-details"/> 
    </authentication-manager> 

</beans:beans> 

我得到以下異常：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined 

但實體管理器Bean與所有定義的servlet-context.xml的 沿有關DBMS連接的信息。

必須注意的是，例如，我可以在控制器中自動裝載DAO類。

的servlet-context.xml的

編輯：

OK我解決了這個問題，我不得不添加sollowing線security.xml文件

<!-- EntityManagerFactory --> 
    <beans:bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory"> 

    <beans:property name="persistenceUnitName" value="myunit" />

    <beans:property name="password" value="root"/> 
    </beans:bean> 

我真的不知道爲什麼，這些info已經包含在servlet-context.xml中 你能幫我理解發生了什麼嗎？

Answer 1

你能檢查您是否已經出現在servlet上下文文件組件掃描標籤，如下

<context:component-scan base-package="your.base.package" />
