我正在使用acegi身份验证进行登录。当我尝试比较数据库的值 我正在使用以下课程
@Transactional(readOnly = true)
@Service
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserDAO userdao;
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
com.quest.model.dto.User dbUser = userdao.searchDatabase(username);
}
}
但是自动连接字段未初始化。 但它在控制器类中初始化。 该类通过spring-security XML
进行映射<

，userDAO看起来像
package com.quest.model.dao; @Repository("userdao") public class UserDAO { ...}
答案 0 :(得分：0)
没有定义名为'userdao'的bean
您必须将xml配置中的UserDao定义为bean或使用@component
注释UserDao类如果您正在关注基于注释的配置，请取消注释config xml
中的以下部分<!--
<context:annotation-config />
<context:component-scan base-package="com.quest.*>" />
<mvc:annotation-driven />
-->

Your web.xml is creating two Spring application contexts. Let's call them Security (after spring-security.xml) and Servlet (after spring-servlet.xml). Security is created by the ContextLoaderListener listener, and Servlet is created by the DispatcherServlet servlet. Security is the parent of Servlet. That means that the beans in Security are only visible to other beans in Security, and the beans in Servlet can see both the beans in Security and in Servlet.
You're defining the CustomUserDetailsService (CUDS) bean in Security, and the UserAccountDao and UserDao beans in Servlet, so the CUDS bean can't see them.
