项目中经常会遇到权限的控制的问题，这次在springboot 中集成security 实现权限控制。

1. 创建spring boot项目用的最新的2.0.4.RELEASE版本，在pom.xml中加入security依赖

<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-security</artifactId>
</dependency>

2.security 自定义

spring security 中提供了专门的配置类WebSecurityConfigurerAdapter，这里需要研究其中的三个方法

    /**
     * 配置用户签名服务 主要是user-details 机制，
     *
     * @param auth 签名管理器构造器，用于构建用户具体权限控制
     * @throws Exception
     */
protected void configure(AuthenticationManagerBuilder auth) throws Exception;
  /**
     * 用来构建 Filter 链
     *
     * @param web
     * @throws Exception
     */
public void configure(WebSecurity web) throws Exception;
/**
     * 用来配置拦截保护的请求
     *
     * @param http
     * @throws Exception
     */
protected void configure(HttpSecurity http) throws Exception;

通过对这三个方法的重写，完成zidi自定义配置。

3.创建 security 自定义配置类WebSecurityConfig

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

   @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        super.configure(auth);
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        super.configure(web);
    }
}


}

4.自定义用户服务信息，这里直接使用数据库签名服务（还有一种内存签名服务，不过只适用于测试开发用，这里直接跳过）。

加入数据源配置：

spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=000000
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.database=mysql
spring.jpa.show-sql=true

加入依赖

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<scope>runtime</scope>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

创建表（这里借鉴了网上的一些博客内容，有优化空间，但是需要根据具体需求调整）

DROP TABLE IF EXISTS `sys_permission`;

CREATE TABLE `sys_permission` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(10) DEFAULT '',
  `descritpion` varchar(10) DEFAULT '',
  `url` varchar(10) DEFAULT '',
  `pid` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8mb4;

/*Data for the table `sys_permission` */

insert  into `sys_permission`(`id`,`name`,`descritpion`,`url`,`pid`) values (3,'ADMIN','','',NULL),(4,'USER','','',NULL);

/*Table structure for table `sys_permission_role` */

DROP TABLE IF EXISTS `sys_permission_role`;

CREATE TABLE `sys_permission_role` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `role_id` int(11) DEFAULT NULL,
  `permission_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4;

/*Data for the table `sys_permission_role` */

insert  into `sys_permission_role`(`id`,`role_id`,`permission_id`) values (1,2,4),(2,1,3);

/*Table structure for table `sys_role` */

DROP TABLE IF EXISTS `sys_role`;

CREATE TABLE `sys_role` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(10) DEFAULT '',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4;

/*Data for the table `sys_role` */

insert  into `sys_role`(`id`,`name`) values (1,'ADMIN'),(2,'USER');

/*Table structure for table `sys_role_user` */

DROP TABLE IF EXISTS `sys_role_user`;

CREATE TABLE `sys_role_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `Sys_user_id` int(11) DEFAULT NULL,
  `sys_role_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4;

/*Data for the table `sys_role_user` */

insert  into `sys_role_user`(`id`,`Sys_user_id`,`sys_role_id`) values (1,2,1),(2,3,2);

/*Table structure for table `sys_user` */

DROP TABLE IF EXISTS `sys_user`;

CREATE TABLE `sys_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(10) DEFAULT NULL,
  `password` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4;

/*Data for the table `sys_user` */

insert  into `sys_user`(`id`,`name`,`password`) values (2,'admin','$2a$10$Yks2LoqzBUHEWjyLCnsdtepI4oCNip9yNdf67y19ewF8geORNAO5m'),(3,'xuweichao','$2a$10$kmFQOKZw8l776qXp00Lq9e2drL5MUSpG9YHnQtQwbVzyUjJQwHNha');

密码是通过密码编辑器生成的。

创建提提对象和Repository

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

    @Id
    @Column(name="id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    //权限名称
    @Column(name="name")
    private String name;

    //权限描述
    @Column(name = "descritpion")
    private String descritpion;

    //授权链接
    @Column(name = "url")
    private String url;

    //父节点id
    @Column(name = "pid")
    private int pid;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public String getDescritpion() {
        return descritpion;
    }

    public void setDescritpion(String descritpion) {
        this.descritpion = descritpion;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public int getPid() {
        return pid;
    }

    public void setPid(int pid) {
        this.pid = pid;
    }
}
@Entity
@Table(name="sys_role")
public class SysRole {

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Column(name = "name")
    private String name;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

@Entity
@Table(name = "sys_user")
public class SysUser {

    @Id
    @Column(name="id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    @Column(name = "name")
    private String name;
    @Column(name = "password")
    private String password;

    @Transient
    private List<SysRole> roles;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public String getPassword() {
        return password;
    }

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

    public List<SysRole> getRoles() {
        return roles;
    }

    public void setRoles(List<SysRole> roles) {
        this.roles = roles;
    }

    @Override
    public String toString() {
        return "SysUser{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", password='" + password + '\'' +
                ", roles=" + roles +
                '}';
    }
}


@Repository
public interface PermissionRepository extends CrudRepository<Permission,Integer> {

}

public interface SysRoleRepository extends CrudRepository<SysRole,Integer> {
}

@Repository
public interface SysUserRepository extends CrudRepository<SysUser,Integer> {

    @Query("select a from SysUser a where a.name=:name")
    public SysUser getUserByName(@Param("name") String name);
}

业务接口及实现

public interface PermissionService {
    public List<Permission> findAll();
    public List<Permission> findByAdminUserId(int userId);
}


@Service
public class PermissionServiceImpl implements PermissionService {

    @Autowired
    PermissionRepository permissionRepository ;

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public List<Permission> findAll() {
        return null;
    }

    @Override
    public List<Permission> findByAdminUserId(int userId) {

        List<Permission> list = new ArrayList<Permission>();
        List<Object[]> abcs = entityManager.createNativeQuery("select p.* \n" +
                "        from Sys_User u\n" +
                "        LEFT JOIN sys_role_user sru on u.id= sru.Sys_User_id\n" +
                "        LEFT JOIN Sys_Role r on sru.Sys_Role_id=r.id\n" +
                "        LEFT JOIN Sys_permission_role spr on spr.role_id=r.id\n" +
                "        LEFT JOIN Sys_permission p on p.id =spr.permission_id\n" +
                "        where u.id="+userId).getResultList();
        for (Object[] abc : abcs) {
            Permission permission = new Permission();
            permission.setId(Integer.valueOf(abc[0]+""));
            permission.setName(abc[1]+"");
            permission.setDescritpion(abc[2]+"");
            permission.setUrl(abc[3]+"");
//            permission.setPid(Integer.valueOf(abc[4]+""));
            list.add(permission);
        }
        return list;
    }
}

5.设置用户权限方式，spring 提供了一个 UserDetailService 接口，通过它可以获取用户信息。

自定义用户服务类

//自定义userdetailservice
@Service
public class UserDetailServiceImpl implements UserDetailsService {

    @Autowired
    SysUserRepository sysUserRepository;
    @Autowired
    PermissionService permissionService;
    @Autowired
    PasswordEncoder passwordEncoder;

    @Transactional
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        SysUser sysUser = sysUserRepository.getUserByName(username);
        List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
        if (sysUser != null) {
            System.err.println("sysUser===============" + sysUser);
            //获取用户的授权
            List<Permission> permissions = permissionService.findByAdminUserId(sysUser.getId());
            //声明授权文件
            for (Permission permission : permissions) {
                if (permission != null && permission.getName() != null) {
                    GrantedAuthority grantedAuthority = new SimpleGrantedAuthority("ROLE_"+permission.getName());
                    grantedAuthorities.add(grantedAuthority);
                }
            }
        }
        System.err.println("grantedAuthorities===============" + grantedAuthorities);
        return new User(sysUser.getName(), sysUser.getPassword(), grantedAuthorities);
    }
}

重写protected void configure(AuthenticationManagerBuilder auth) throws Exception 方法。

 @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

  
    /**
     * 配置用户签名服务 主要是user-details 机制，
     *
     * @param auth 签名管理器构造器，用于构建用户具体权限控制
     * @throws Exception
     */
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
                .passwordEncoder(passwordEncoder());
    }

6.限制请求 重写 protected void configure(HttpSecurity http) throws Exception

 http.csrf().disable()//禁用了 csrf 功能
                .authorizeRequests()//限定签名成功的请求
                .antMatchers("/decision/**","/govern/**").hasAnyRole("USER","ADMIN")//对decision和govern 下的接口 需要 USER 或者 ADMIN 权限
                .antMatchers("/admin/login").permitAll()///admin/login 不限定
                .antMatchers("/admin/**").hasRole("ADMIN")//对admin下的接口 需要ADMIN权限
                .antMatchers("/oauth/**").permitAll()//不拦截 oauth 开放的资源
                .anyRequest().permitAll()//其他没有限定的请求，允许访问
                .and().anonymous()//对于没有配置权限的其他请求允许匿名访问
                .and().formLogin()//使用 spring security 默认登录页面
                .and().httpBasic();//启用http 基础验证
}

然后创建几个接口，进行测试。

@RestController
@RequestMapping("admin")
public class MainController {


    @RequestMapping("/")
    public String index(){

        return "index" ;
    }

    @RequestMapping("/detail")
    public String hello(){
        return "hello" ;
    }

    @RequestMapping("/login")
    public String login() {
        return "login";
    }

这里就整合完成了。

后续会加入 OAUTH2.0 做安全认证，敬请期待。
