SpringBoot整合Spring Security登录表单详

部分引自 www.javaboy.org
在 formLogin这里还可以配置详细一点

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("yzn").password("123").roles("admin")
                .and()
                .withUser("test").password("123").roles("user");
    }

    @Bean
    PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .antMatchers("/user/**").hasAnyRole("admin", "user")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                // 登录处理接口
                .loginProcessingUrl("/doLogin")
                // 定义登录页面，未登录时，访问一个需要登录之后才能访问的接口，会自动跳转到该页面
                .loginPage("/login")
                //定义登录时，用户名的 key，默认为 username
                .usernameParameter("uname")
                //定义登录时，用户密码的 key，默认为 password
                .passwordParameter("passwd")
                //登录成功的处理器
                .successHandler(new AuthenticationSuccessHandler() {
                    @Override
                    public void onAuthenticationSuccess(HttpServletRequest req, HttpServletResponse res, Authentication authentication) throws IOException, ServletException {
                        res.setContentType("application/json;charset=utf-8");
                        PrintWriter out = res.getWriter();
                        out.write("success");
                        out.flush();
                    }
                })
                .failureHandler(new AuthenticationFailureHandler() {
                    @Override
                    public void onAuthenticationFailure(HttpServletRequest req, HttpServletResponse res, AuthenticationException e) throws IOException, ServletException {
                        res.setContentType("application/json;charset=utf-8");
                        PrintWriter out = res.getWriter();
                        out.write("fail");
                        out.flush();
                    }
                })
                //和表单登录相关的接口统统都直接通过
                .permitAll()
                .and()
                .csrf().disable();
    }
}

@RestController
public class HelloController {

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

    @GetMapping("/admin/hello")
    public String admin() {
        return "hello admin";
    }

    @GetMapping("/user/hello")
    public String user() {
        return "hello user";
    }

    @GetMapping("/login")
    public String login() {
        return "please login!!!";
    }
}

利用postman测试

注销表单配置

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("yzn").password("123").roles("admin")
                .and()
                .withUser("test").password("123").roles("user");
    }

    @Bean
    PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .antMatchers("/user/**").hasAnyRole("admin", "user")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                // 登录处理接口
                .loginProcessingUrl("/doLogin")
                // 定义登录页面，未登录时，访问一个需要登录之后才能访问的接口，会自动跳转到该页面
                .loginPage("/login")
