⼆，配置过滤规则（类似配置shiro中的ShiroFilterFactoryBean）
⼤致内容：配置⼀些登录的跳转，及权限、登录验证的跳转规则。和记住我实现⾃动登录的配置。/**
* @author 张⼦⾏
* @class WebSecurityConfigurerAdapter
*/
@Configuration
public class SecurityConfigTest extends WebSecurityConfigurerAdapter{
@Autowired
private UserDetailsService userDetailsService;
//注⼊数据源
@Autowired
private DataSource dataSource;
/**
* @param
* @method 配置登录记住我，记住我相关的底层数据库的相关配置，⽣成的token存储在⾥⾯
*/
@Bean
public PersistentTokenRepository persistentTokenRepository(){
JdbcTokenRepositoryImpl jdbcTokenRepository =new JdbcTokenRepositoryImpl();
jdbcTokenRepository.setDataSource(dataSource);
//开启后token会存储在这张表⾥⾯
//jdbcTokenRepository.setCreateTableOnStartup(true);
return jdbcTokenRepository;
}
/
**
* @param
* @method 配置授权认证逻辑
*/
@Override
protected void configure(AuthenticationManagerBuilder auth)throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(password());
}
/**
/**
* @param
* @method 密码加密规则
*/
@Bean
PasswordEncoder password(){
return new BCryptPasswordEncoder();
}
/**
* @param
* @method 配置过滤规则 url层⾯
*/
@Override
protected void configure(HttpSecurity http)throws Exception {
//退出
http.logout().logoutUrl("/logout").
logoutSuccessUrl("/test/hello").permitAll();
//配置没有权限访问跳转⾃定义页⾯
http.authorizeRequests()
.antMatchers("/","/test/hello","/user/login").permitAll()//设置哪些路径可以直接访问，不需要认证//当前登录⽤户，只有具有admins权限才可以访问这个路径
//1 hasAuthority⽅法
// .antMatchers("/test/index").hasAuthority("admins")
//2 hasAnyAuthority⽅法
// .antMatchers("/test/index").hasAnyAuthority("admins,manager")
//3 hasRole⽅法  ROLE_sale
.antMatchers("/test/index").hasRole("sale")
.anyRequest().authenticated();
//配置登录的相关
http.formLogin()//⾃定义⾃⼰编写的登录页⾯
.loginPage("/on.html")//登录页⾯设置
.loginProcessingUrl("/user/login")//登录访问路径
.defaultSuccessUrl("/success.html").permitAll()//登录成功之后，跳转路径
.failureUrl("/unauth.html");
//配置⾃动登录记住我
.tokenRepository(persistentTokenRepository())
.tokenValiditySeconds(60).userDetailsService(userDetailsService);
//关闭csrf防护springmvc常用标签
http.csrf().disable();
}
}
三，编写登录认证逻辑
⼤体逻辑：根据⽤户名查询⽤户信息，及其权限返回
* @class UserDetailsService
*/
@Service("userDetailsService")
public class MyUserDetailsService implements UserDetailsService{
@Autowired
private UsersMapper usersMapper;
/**
* @param
* @method 登录逻辑
*/
@Override
public UserDetails loadUserByUsername(String username)throws UsernameNotFoundException {
//调⽤usersMapper⽅法，根据⽤户名查询数据库
QueryWrapper<User> wrapper =new QueryWrapper();
// where username=?
wrapper.eq("username", username);
User user = usersMapper.selectOne(wrapper);
//判断
if(user == null){//数据库没有⽤户名，认证失败
throw new UsernameNotFoundException("⽤户名不存在！");
}
//⾓⾊要加前缀ROLE_ ，权限直接没啥要求
List<GrantedAuthority> auths =
AuthorityUtilsmaSeparatedStringToAuthorityList("admins,ROLE_sale");
/
/从查询数据库返回users对象，得到⽤户名和密码，返回
return new org.userdetails.Username(),
new BCryptPasswordEncoder().Password()), auths);
}
}
四，编写html页⾯
主要写下登录页⾯，注意这⾥的action="/user/login"就是我们配置过的登录的请求action
<h1>static表单提交11</h1>
<!-- 表单提交⽤户信息，注意字段的设置，直接是*{} -->
<form action="/user/login"method="post">
<input type="text"name="username"/>
<input type="text"name="password"/>
<input type="checkbox"name="remember-me"/>⾃动登录
<input type="submit"/>
</form>
五，编写controller
⼤体对以下的注解做了个测试
注解作⽤可选参数
@PreAuthorize在⼊⽅法之前拦截hasPermission()，hasRole()，hasAnyAuthority()，hasAnyRole()，hasAuthority()
@PostAuthorize 在出⽅法之前拦截 ，如果没有相关权限，
虽执⾏⽅法但是还是没有通过认证，返回
页⾯显⽰没有权限
hasPermission()，hasRole()，hasAnyAuthority()，hasAnyRole()，hasAuthority()
@PostFilter只返回指定的model信息filterObject.username == ‘zzh’
* @class TestController
*/
@RestController
@RequestMapping("/test")
public class TestController{
@GetMapping("hello")
public String hello(){
return"hello security";
}
@GetMapping("index")
public String index(){
return"hello index";
}
@GetMapping("update")
//@Secured({"ROLE_sale","ROLE_manager"}) @PreAuthorize("hasAnyAuthority('admins')")
@PostAuthorize("hasAnyAuthority('admins1')") public String update(){
System.out.println("");
return"hello update";
}
@GetMapping("getAll")
@PostAuthorize("hasAnyAuthority('admins')")
@PostFilter("filterObject.username == 'admin1'") public List<User>getAllUser(){
ArrayList<User> list =new ArrayList<>();
User user =new User();
user.setId(1);
user.setPassword("666");
user.setUsername("zzh");
list.add(user);
return list;
}
}
六，测试
1：输⼊任何url都要求登录
