配置Security

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception{
        //路由策略和访问的简单配置
        httpSecurity
                .formLogin() //启动默认登录
                .failureUrl("/login?error")   //失败跳转页面
                .defaultSuccessUrl("/helloSpringboot") // 成功跳转页面
                .permitAll();           //登录页面全部权限可访问
        super.configure(httpSecurity);
    }

    /**
     * 配置内存用户
     */
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception{
        /*auth
                .inMemoryAuthentication()
                .withUser("xiaoli").password("123").roles("ADMIN")
                .and()
                .withUser("xiaoming").password("123").roles("USER");*/
        auth
                .inMemoryAuthentication()
                .passwordEncoder(new MyPasswordEncoder())
                .withUser("xiaoming").password("123").roles("ADMIN")
                .and()
                .passwordEncoder(new MyPasswordEncoder())
                .withUser("xiaolizi").password("123").roles("USER");
    }
}

上面是原始的，在新版本更新后 官方不推荐不加密 所以只能自己构造一个没有加密的。

public class MyPasswordEncoder implements PasswordEncoder {
    @Override
    public String encode(CharSequence charSequence) {
        return charSequence.toString();
    }
    @Override
    public boolean matches(CharSequence charSequence, String s) {
        return s.equals(charSequence.toString());
    }
}

不这样写会出现一直出现There is no PasswordEncoder mapped for the id “null” 这样的问题。

• @EnableWebSecurity 开启Security安全框架
