shiro(二) 表問題

通常狀況下使用三張表，用戶表user、角色表role、權限表permission

 

表結構及關係以下圖

Hibernate對應的pojo以下

user

package com.shiro.pojo;

import java.util.HashSet;
import java.util.List;
import java.util.Set;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;
import javax.persistence.Transient;



@Entity
@Table(name="t_user")
public class User {

    private Integer id;
    private String username;
    private String password;
    private List<Role> roleList;//一個用戶具備多個角色

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    @ManyToMany
    @JoinTable(name="t_user_role",joinColumns={@JoinColumn(name="user_id")},inverseJoinColumns={@JoinColumn(name="role_id")})
    public List<Role> getRoleList() {
        return roleList;
    }
    public void setRoleList(List<Role> roleList) {
        this.roleList = roleList;
    }

    @Transient
    public Set<String> getRolesName(){
        List<Role> roles=getRoleList();
        Set<String> set=new HashSet<String>();
        for (Role role : roles) {
            set.add(role.getRolename());
        }
        return set;
    }

}

role

 

package com.shiro.pojo;
import java.util.ArrayList;
import java.util.List;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import javax.persistence.Transient;

@Entity
@Table(name="t_role")
public class Role {

    private Integer id;
    private String rolename;
    private List<Permission> permissionList;//一個角色對應多個權限
    private List<User> userList;//一個角色對應多個用戶

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getRolename() {
        return rolename;
    }
    public void setRolename(String rolename) {
        this.rolename = rolename;
    }
    @OneToMany(mappedBy="role")
    public List<Permission> getPermissionList() {
        return permissionList;
    }
    public void setPermissionList(List<Permission> permissionList) {
        this.permissionList = permissionList;
    }
    @ManyToMany
    @JoinTable(name="t_user_role",joinColumns={@JoinColumn(name="role_id")},inverseJoinColumns={@JoinColumn(name="user_id")})
    public List<User> getUserList() {
        return userList;
    }
    public void setUserList(List<User> userList) {
        this.userList = userList;
    }

    @Transient
    public List<String> getPermissionsName(){
        List<String> list=new ArrayList<String>();
        List<Permission> perlist=getPermissionList();
        for (Permission per : perlist) {
            list.add(per.getPermissionname());
        }
        return list;
    }
}

permission

package com.shiro.pojo;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="t_permission")
public class Permission {

    private Integer id;
    private String permissionname;
    private Role role;//一個權限對應一個角色

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getPermissionname() {
        return permissionname;
    }
    public void setPermissionname(String permissionname) {
        this.permissionname = permissionname;
    }
    @ManyToOne
    @JoinColumn(name="role_id")
    public Role getRole() {
        return role;
    }
    public void setRole(Role role) {
        this.role = role;
    }

}

user與role是多對多關係  產生t_user_role爲中間表
