public class KungfuController {
private final String PREFIX = "pages/";
@RequestMapping("/")
public String index() {
System.out.println("hello word");
return "welcome";
}
@RequestMapping("/userlogin")
public String loginPage() {
return PREFIX+"login1";
}
@GetMapping("/level1/{path}")
public String level1(@PathVariable("path")String path) {
return PREFIX+"level1/"+path;
}
@GetMapping("/level2/{path}")
public String level2(@PathVariable("path")String path) {
return PREFIX+"level2/"+path;
}
@GetMapping("/level3/{path}")
public String level3(@PathVariable("path")String path) {
return PREFIX+"level3/"+path;
}}
//配置下
@EnableWebSecurity public class mySecurity extends WebSecurityConfigurerAdapter {
//为啥引入这个bean ，因为在securety在5.0后使用系统的登录模板，默认把密码给加密啦，这个写的是不让密码加密
@Bean
public static NoOpPasswordEncoder passwordEncoder() {
return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
}
protected void configure(HttpSecurity http) throws Exception {
//定制请求的授权规则
http.authorizeRequests().antMatchers("/").permitAll()
.antMatchers("/level1/**").hasRole("VIP1")
.antMatchers("/level2/**").hasRole("VIP2")
.antMatchers("/level3/**").hasRole("VIP3");
//开启自动登录的功能
http.formLogin();
//开启自动配置的注销功能
http.logout().logoutSuccessUrl("/");
}
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("mao").password("123").roles("VIP1","VIP2")
.and().withUser("zhang").password("123").roles("VIP1","VIP3").and()
.withUser("li").password("123").roles("VIP2","VIP3");
}} //该模板都是尚学堂的
