Spring Security应用实例（一）：用户登录

SecuritySpring应用服务器BeanHibernate 
阅读更多

经过Spring Security官方文档及相关资料的学习，自己做了一个简单的用户登录模块，现在将自己写的代码整理处理，以供大家参考或交流，如有不对，请指正错误。

1、库表建立

     1）用户表

DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `id` int(10) NOT NULL auto_increment,
  `login_name` varchar(20) default NULL,
  `password` varchar(20) default NULL,
  `name` varchar(20) default NULL,
  `email` varchar(30) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

     2）角色表

DROP TABLE IF EXISTS `roles`;
CREATE TABLE `roles` (
  `id` int(10) NOT NULL auto_increment,
  `name` varchar(20) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

     3）权限表

DROP TABLE IF EXISTS `authorities`;
CREATE TABLE `authorities` (
  `id` int(10) NOT NULL auto_increment,
  `name` varchar(20) default NULL,
  `display_name` varchar(20) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

     4）用户-角色表

DROP TABLE IF EXISTS `users_roles`;
CREATE TABLE `users_roles` (
  `user_id` int(10) NOT NULL,
  `role_id` int(10) NOT NULL,
  PRIMARY KEY  (`user_id`,`role_id`),
  KEY `FK_R_2` (`role_id`),
  CONSTRAINT `FK_R_1` FOREIGN KEY (`user_id`) REFERENCES `users` (`id`),
  CONSTRAINT `FK_R_2` FOREIGN KEY (`role_id`) REFERENCES `roles` (`id`)

 

    5）角色-权限表

DROP TABLE IF EXISTS `roles_authorities`;
CREATE TABLE `roles_authorities` (
  `role_id` int(10) NOT NULL,
  `authority_id` int(10) NOT NULL,
  PRIMARY KEY  (`role_id`,`authority_id`),
  KEY `FK_R_4` (`authority_id`),
  CONSTRAINT `FK_R_3` FOREIGN KEY (`role_id`) REFERENCES `roles` (`id`),
  CONSTRAINT `FK_R_4` FOREIGN KEY (`authority_id`) REFERENCES `authorities` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 

2、建立Pojo类

     1）用户

package cn.com.sunjiesh.springmvcdemo.entity;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;

/**
 * 统一定义id的entity基类.
 * 
 * @author calvin
 */
@MappedSuperclass
public class IdEntity {

	private Long id;

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}
}
  
package cn.com.sunjiesh.springmvcdemo.entity.user;

import java.util.LinkedHashSet;
import java.util.List;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.OrderBy;
import javax.persistence.Table;
import javax.persistence.Transient;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import org.hibernate.annotations.Fetch;
import org.hibernate.annotations.FetchMode;
import org.springside.modules.utils.CollectionUtils;

import cn.com.sunjiesh.springmvcdemo.entity.IdEntity;

/**
 * 用户.
 * 
 * 注意@Cache(Entity与集合的缓存),@ManyToMany/@JoinTable(多对多关系),@OrderBy/LinkedHashSet(集合排序),@Transient(非持久化属性)的应用.
 * 
 * @author calvin
 */
@Entity
@Table(name = "USERS")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User extends IdEntity {

	private String loginName;

	private String password;

	private String name;

	private String email;

	private Set<Role> roles = new LinkedHashSet<Role>();

	@Column(name="login_name")
	public String getLoginName() {
		return loginName;
	}

	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}

	@Column(name="password")
	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	@Column(name="name")
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Column(name="email")
	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	@ManyToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE },fetch=FetchType.EAGER)
	@JoinTable(name = "USERS_ROLES", joinColumns = { @JoinColumn(name = "USER_ID") }, inverseJoinColumns = { @JoinColumn(name = "ROLE_ID") })
	@OrderBy("id")
	@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
	public Set<Role> getRoles() {
		return roles;
	}

	public void setRoles(Set<Role> roles) {
		this.roles = roles;
	}

	@Transient
	public String getRoleNames() throws Exception {
		return CollectionUtils.fetchPropertyToString(roles, "name", ", ");
	}

	@SuppressWarnings("unchecked")
	@Transient
	public List<Long> getRoleIds() throws Exception {
		return CollectionUtils.fetchPropertyToList(roles, "id");
	}

	@Override
	public String toString() {
		return ToStringBuilder.reflectionToString(this);
	}
}
 

     2）角色

package cn.com.sunjiesh.springmvcdemo.entity.user;

import java.util.LinkedHashSet;
import java.util.List;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.OrderBy;
import javax.persistence.Table;
import javax.persistence.Transient;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import org.springside.modules.utils.CollectionUtils;

import cn.com.sunjiesh.springmvcdemo.entity.IdEntity;

/**
 * 角色.
 * 
 * 注意@Cache(Entity与集合的缓存),@ManyToMany/@JoinTable(多对多关系),@OrderBy/LinkedHashSet(集合排序),@Transient(非持久化属性)的应用.
 * 
 * @author calvin
 */
@Entity
@Table(name = "ROLES")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Role extends IdEntity {

	private String name;

	private Set<Authority> auths = new LinkedHashSet<Authority>();

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@ManyToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE },fetch=FetchType.EAGER)
	@JoinTable(name = "ROLES_AUTHORITIES", joinColumns = { @JoinColumn(name = "ROLE_ID") }, inverseJoinColumns = { @JoinColumn(name = "AUTHORITY_ID") })
	@OrderBy("id")
	@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
	public Set<Authority> getAuths() {
		return auths;
	}

	public void setAuths(Set<Authority> auths) {
		this.auths = auths;
	}

	@Transient
	public String getAuthNames() throws Exception {
		return CollectionUtils.fetchPropertyToString(auths, "displayName", ", ");
	}

	@SuppressWarnings("unchecked")
	@Transient
	public List<Long> getAuthIds() throws Exception {
		return CollectionUtils.fetchPropertyToList(auths, "id");
	}

	@Override
	public String toString() {
		return ToStringBuilder.reflectionToString(this);
	}
}
 

     3）权限

package cn.com.sunjiesh.springmvcdemo.entity.user;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

import cn.com.sunjiesh.springmvcdemo.entity.IdEntity;

/**
 * 权限.
 * 
 * @Cache使用READ_ONLY策略.
 * 
 * @author calvin
 */
@Entity
@Table(name = "AUTHORITIES")
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public class Authority extends IdEntity {

	private String name;

	private String displayName;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Column(name="display_name")
	public String getDisplayName() {
		return displayName;
	}

	public void setDisplayName(String displayName) {
		this.displayName = displayName;
	}

	@Override
	public String toString() {
		return ToStringBuilder.reflectionToString(this);
	}
}
 

     注意：@ManyToMany中的fetch=FetchType.EAGER。如果fetch=FetchType.LAZY会报异常。

3、建立DAO类

    1）接口

 

package cn.com.sunjiesh.springmvcdemo.dao.iface;

import cn.com.sunjiesh.springmvcdemo.entity.user.User;



/**
 * 
 * @author sunjie
 * @since 2009-03-29
 * 
 */
public interface IUserDAO extends IBaseHibernateDAO<User> {

	public User getUserByUserName(String username);

}
 

    2）实现类

package cn.com.sunjiesh.springmvcdemo.dao.impl;

import org.apache.log4j.Logger;
import org.hibernate.Query;


import cn.com.sunjiesh.springmvcdemo.dao.iface.IUserDAO;
import cn.com.sunjiesh.springmvcdemo.entity.user.User;

public class UserDAOImpl extends BaseHibernateDAOImpl<User> implements IUserDAO {

	private static Logger LOG = Logger.getLogger(UserDAOImpl.class);

	public User getUserByUserName(String username) {
		String hql = "from User where loginName = ?";
		Query query = getSession().createQuery(hql);
		query.setParameter(0, username);
		User user = (User) query.list().get(0);
		return user;
	}

}

 

4、Spring Security相关代码

package cn.com.sunjiesh.springmvcdemo.service.security;

import java.util.ArrayList;
import java.util.List;

import org.apache.log4j.Logger;
import org.springframework.dao.DataAccessException;
import org.springframework.security.GrantedAuthority;
import org.springframework.security.GrantedAuthorityImpl;

import org.springframework.security.userdetails.UserDetails;
import org.springframework.security.userdetails.UserDetailsService;
import org.springframework.security.userdetails.UsernameNotFoundException;

import cn.com.sunjiesh.springmvcdemo.dao.iface.IUserDAO;
import cn.com.sunjiesh.springmvcdemo.entity.user.Authority;
import cn.com.sunjiesh.springmvcdemo.entity.user.Role;
import cn.com.sunjiesh.springmvcdemo.entity.user.User;



/**
 * 实现SpringSecurity的UserDetailsService接口,获取用户Detail信息.
 * @author calvin
 */
public class UserDetailServiceImpl implements UserDetailsService{

	private static Logger LOG=Logger.getLogger(UserDetailServiceImpl.class);
	
	private IUserDAO userDao;
	
	public UserDetails loadUserByUsername(String username)
			throws UsernameNotFoundException, DataAccessException {
		if(username==null){
			LOG.error("username is null");
		}
		if(userDao==null){
			LOG.error("userDao is null");
		}
		User user=userDao.getUserByUserName(username);
		//TOTO 判断用户存在，如果不存在，则抛出异常。
		if(user==null){
			LOG.error(username+" is not exist", new UsernameNotFoundException(username+" is not exist"));
		}
		
		List<GrantedAuthority> authsList = new ArrayList<GrantedAuthority>();
		
		System.out.println("user.getRoles().size()="+user.getRoles().size());
		for (Role role : user.getRoles()) {
			for (Authority authority : role.getAuths()) {
				authsList.add(new GrantedAuthorityImpl(authority.getName()));
			}
		}
		
		//TODO　
		org.springframework.security.userdetails.User userdetail = new org.springframework.security.userdetails.User(
				user.getLoginName(), user.getPassword(), true, true, true, true, authsList
						.toArray(new GrantedAuthority[authsList.size()]));

		return userdetail;
	}

	public void setUserDao(IUserDAO userDao) {
		this.userDao = userDao;
	}
}
 

5、配置文件

		最后，有投票者根据用户持有认证和访问url需要的属性，调用自己的voter来投票，决定是否允许访问。
