篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了请教Apache Shiro 与spring3登录问题相关的知识，希望对你有一定的参考价值。
参考技术A public class ShiroDbRealm extends AuthorizingRealm@Autowired
private AuthUserManager authUserManager;
/**
* 认证回调函数,登录时调用.
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException
UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
AuthUser user = authUserManager.getMember(token.getUsername());
if (user != null)
if (!user.getEnabled().equals(1))
throw new DisabledAccountException();
return new SimpleAuthenticationInfo(new ShiroUser(user.getUserName(), user.getNickName()), user.getPassword(), getName());
else
return null;
/**
* 授权查询回调函数, 进行鉴权但缓存中无用户的授权信息时调用.
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals)
ShiroUser shiroUser = (ShiroUser) principals.getPrimaryPrincipal();
AuthUser user = authUserManager.getMember(shiroUser.loginName);
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
List<String> permissionList = new ArrayList<String>();
......
return info;
/**
* 设定Password校验的Hash算法与迭代次数.
*/
@PostConstruct
public void initCredentialsMatcher()
HashedCredentialsMatcher matcher = new HashedCredentialsMatcher(Md5Hash.ALGORITHM_NAME);
// matcher.setHashIterations(1);
setCredentialsMatcher(matcher);
......
Spring Boot使用Shiro实现登录授权认证
1、Shiro是Apache下的一个开源项目，我们称之为Apache Shiro。它是一个很易用与Java项目的的安全框架，提供了认证、授权、加密、会话管理，与spring Security 一样都是做一个权限的安全框架，但是与Spring Security 相比，在于 Shiro 使用了比较简单易懂易于使用的授权方式。shiro属于轻量级框架，相对于security简单的多，也没有security那么复杂。所以我这里也是简单介绍一下shiro的使用。
2、非常简单；其基本功能点如下图所示：
Authentication：身份认证/登录，验证用户是不是拥有相应的身份；
Authorization：授权，即权限验证，验证某个已认证的用户是否拥有某个权限；即判断用户是否能做事情，常见的如：验证某个用户是否拥有某个角色。或者细粒度的验证某个用户对某个资源是否具有某个权限；
Session Manager：会话管理，即用户登录后就是一次会话，在没有退出之前，它的所有信息都在会话中；会话可以是普通JavaSE环境的，也可以是如Web环境的；
Cryptography：加密，保护数据的安全性，如密码加密存储到数据库，而不是明文存储；
Web Support：Web支持，可以非常容易的集成到Web环境；
Caching：缓存，比如用户登录后，其用户信息、拥有的角色/权限不必每次去查，这样可以提高效率；
Concurrency：shiro支持多线程应用的并发验证，即如在一个线程中开启另一个线程，能把权限自动传播过去；
Testing：提供测试支持；
Run As：允许一个用户假装为另一个用户（如果他们允许）的身份进行访问；
Remember Me：记住我，这个是非常常见的功能，即一次登录后，下次再来的话不用登录了。
记住一点，Shiro不会去维护用户、维护权限；这些需要我们自己去设计/提供；然后通过相应的接口注入给Shiro即可。
3、这里我就简单介绍一下springboot和shiro整合与基本使用。
1）目录结构
2）需要的基础包：pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</dependency>
<dependency>
<groupId>mysql</groupId>

<version>5.1.9</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.4</version>
</dependency>
</dependencies>
</project>
3）基本配置application.yml
server:
port: 8082
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/spring_shiro?useUnicode=true&characterEncoding=UTF-8
username: root
password: root
type: com.alibaba.druid.pool.DruidDataSource
jpa:
show-sql: true
hibernate:
ddl-auto: update
http:
encoding:
charset: utf-8
enabled: true
4）这里我们基本需要3个实体，用户，角色和权限
(1)角色：User.class
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(unique = true)
private String name;
private Integer password;
@OneToMany(cascade = CascadeType.ALL,mappedBy = "user")
private List<Role> roles;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Role> getRoles() {
return roles;
}
public void setRoles(List<Role> roles) {
this.roles = roles;
}
public Integer getPassword() {
return password;
}
public void setPassword(Integer password) {
this.password = password;
}
}
注：这里我只考虑一个用户对多个角色，不考虑多对多的关系
(2)角色：Role.class
@Entity
public class Role {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String roleName;
@ManyToOne(fetch = FetchType.EAGER)
private User user;
@OneToMany(cascade = CascadeType.ALL,mappedBy = "role")
private List<Permission> permissions;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getRoleName() {
return roleName;
}
public void setRoleName(String roleName) {
this.roleName = roleName;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public List<Permission> getPermissions() {
return permissions;
}
public void setPermissions(List<Permission> permissions) {
this.permissions = permissions;
}
}
(3)权限：Permission.class
@Entity
public class Permission {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String permission;
@ManyToOne(fetch = FetchType.EAGER)
private Role role;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getPermission() {
return permission;
}
public void setPermission(String permission) {
this.permission = permission;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
}
5）然后就是配置对应的验证，以及过滤条件
(1)验证，以及权限的添加MyShiroRealm.class
//实现AuthorizingRealm接口用户用户认证
public class MyShiroRealm extends AuthorizingRealm{
//用于用户查询
@Autowired
private ILoginService loginService;
//角色权限和对应权限添加
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
//获取登录用户名
String name= (String) principalCollection.getPrimaryPrincipal();
//查询用户名称
User user = loginService.findByName(name);
//添加角色和权限
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
for (Role role:user.getRoles()) {
//添加角色
simpleAuthorizationInfo.addRole(role.getRoleName());
for (Permission permission:role.getPermissions()) {
//添加权限
simpleAuthorizationInfo.addStringPermission(permission.getPermission());
}
}
return simpleAuthorizationInfo;
}
//用户认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
//加这一步的目的是在Post请求的时候会先进认证，然后在到请求
if (authenticationToken.getPrincipal() == null) {
return null;
}
//获取用户信息
String name = authenticationToken.getPrincipal().toString();
User user = loginService.findByName(name);
if (user == null) {
//这里返回后会报出对应异常
return null;
} else {
//这里验证authenticationToken和simpleAuthenticationInfo的信息
SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(name, user.getPassword().toString(), getName());
return simpleAuthenticationInfo;
}
}
}
(2)过滤配置：ShiroConfiguration.class
@Configuration
public class ShiroConfiguration {
//将自己的验证方式加入容器
@Bean
public MyShiroRealm myShiroRealm() {
MyShiroRealm myShiroRealm = new MyShiroRealm();
return myShiroRealm;
}
//权限管理，配置主要是Realm的管理认证
@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(myShiroRealm());
return securityManager;
}
//Filter工厂，设置对应的过滤条件和跳转条件
@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager);
Map<String,String> map = new HashMap<String, String>();
//登出
map.put("/logout","logout");
//对所有用户认证
map.put("/**","authc");
//登录
shiroFilterFactoryBean.setLoginUrl("/login");
//首页
shiroFilterFactoryBean.setSuccessUrl("/index");
//错误页面，认证不通过跳转
shiroFilterFactoryBean.setUnauthorizedUrl("/error");
shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
return shiroFilterFactoryBean;
}
//加入注解的使用，不加入这个注解不生效
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
}
6）接下来就是数据访问层、业务层、以及控制层
(1)数据层：BaseRepository.class,UserRepository.class,RoleRepository.class
@NoRepositoryBean
public interface BaseRepository<T,I extends Serializable> extends PagingAndSortingRepository<T,I>,JpaSpecificationExecutor<T>{
}
public interface UserRepository extends BaseRepository<User,Long>{
User findByName(String name);
}
public interface RoleRepository extends BaseRepository<Role,Long> {
}
(2)业务层：LoginServiceImpl.class
@Service
@Transactional
public class LoginServiceImpl implements ILoginService {
@Autowired
private UserRepository userRepository;
@Autowired
private RoleRepository roleRepository;
//添加用户
@Override
public User addUser(Map<String, Object> map) {
User user = new User();
user.setName(map.get("username").toString());
user.setPassword(Integer.valueOf(map.get("password").toString()));
userRepository.save(user);
return user;
}
//添加角色
@Override
public Role addRole(Map<String, Object> map) {
User user = userRepository.findOne(Long.valueOf(map.get("userId").toString()));
Role role = new Role();
role.setRoleName(map.get("roleName").toString());
role.setUser(user);
Permission permission1 = new Permission();
permission1.setPermission("create");
permission1.setRole(role);
Permission permission2 = new Permission();
permission2.setPermission("update");
permission2.setRole(role);
List<Permission> permissions = new ArrayList<Permission>();
permissions.add(permission1);
permissions.add(permission2);
role.setPermissions(permissions);
roleRepository.save(role);
return role;
}
//查询用户通过用户名
@Override
public User findByName(String name) {
return userRepository.findByName(name);
}
}
(3)控制层：LoginResource.class
@RestController
public class LoginResource {
@Autowired
private ILoginService loginService;
//退出的时候是get请求，主要是用于退出
@RequestMapping(value = "/login",method = RequestMethod.GET)
public String login(){
return "login";
}
//post登录
@RequestMapping(value = "/login",method = RequestMethod.POST)
public String login(@RequestBody Map map){
//添加用户认证信息
Subject subject = SecurityUtils.getSubject();
UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(
map.get("username").toString(),
map.get("password").toString());
//进行验证，这里可以捕获异常，然后返回对应信息
subject.login(usernamePasswordToken);
return "login";
}
@RequestMapping(value = "/index")
public String index(){
return "index";
}
//登出
@RequestMapping(value = "/logout")
public String logout(){
return "logout";
}
//错误页面展示
@RequestMapping(value = "/error",method = RequestMethod.POST)
public String error(){
return "error ok!";
}
//数据初始化
@RequestMapping(value = "/addUser")
public String addUser(@RequestBody Map<String,Object> map){
User user = loginService.addUser(map);
return "addUser is ok! \\n" + user;
}
//角色初始化
@RequestMapping(value = "/addRole")
public String addRole(@RequestBody Map<String,Object> map){
Role role = loginService.addRole(map);
return "addRole is ok! \\n" + role;
}
//注解的使用
@RequiresRoles("admin")
@RequiresPermissions("create")
@RequestMapping(value = "/create")
public String create(){
return "Create success!";
}
}
注：这里对于注解的使用，在最后一个很重要!
7）shiro的使用基本上就是这样子了，主要是权限的控制，其他的主要是做跳转和切换使用
8）最后配上数据库信息：结合控制层观看
user:
role:
permission:
