MySql表的设计:
d1.PNG
没有设置外键，使用user_role来保存用户对应的角色，查询用户时需要使用关联查询
<select id="getAllUsers" resultMap="userMap">
select u.*
,r.name
from user u
LEFT JOIN user_role sru on u.id= sru.userID
LEFT JOIN role r on sru.roldID=r.id
</select>
基本流程：
前端页面基本都是发送Ajax请求来获取Json数据，之后使用LayUI来进行渲染，请求页面的Url都在WebMvcConfig里面，Controller存放的都是返回Json数据格式的处理类
Spirng Security 核心配置类:
配置了访问权限，表单验证处理页面和Url以及验证成功以及失败的处理Handler，登出处理Handler，无权限访问时的处理Handler
public class BrowerSecurityConfig extends WebSecurityConfigurerAdapter {
private final static BCryptPasswordEncoder ENCODER = new BCryptPasswordEncoder();
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
@Bean
public MyUserDetailService myUserDetailService(){
return new MyUserDetailService();
}
@Autowired
private UserLoginAuthenticationFailureHandler userLoginAuthenticationFailureHandler;
@Autowired
private UserLoginAuthenticationSuccessHandler userLoginAuthenticationSuccessHandler;
@Autowired
private UserLogoutSuccessHandler userLogoutSuccessHandler;
@Autowired
private UserAuthenticationAccessDeniedHandler userAuthenticationAccessDeniedHandler;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.headers().frameOptions().sameOrigin()//设置弹出层
.and()
.authorizeRequests()
.antMatchers("/admin/**","/setUserAdmin","/setUser","/deleteUserById")
.access("hasRole('ROLE_ADMIN')")//只有管理员才能访问
.antMatchers("/home","/static/**","/getAllUser","/register_page",
"/register","/checkNameIsExistOrNot")//静态资源等不需要验证
.permitAll()//不需要身份认证
.anyRequest().authenticated()//其他路径必须验证身份
.and()
.formLogin()
.loginPage("/login_page")//登录页面
.loginProcessingUrl("/login")
.usernameParameter("username")
.passwordParameter("password")
.failureHandler(userLoginAuthenticationFailureHandler)//验证失败处理
.successHandler(userLoginAuthenticationSuccessHandler)//验证成功处理
.permitAll()//登录页面不需要验证
.and()
.logout()
.logoutSuccessHandler(userLogoutSuccessHandler)//登出处理
.permitAll()
.and()
.csrf().disable()
.exceptionHandling().accessDeniedHandler(userAuthenticationAccessDeniedHandler);//无权限时的处理
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(myUserDetailService()).passwordEncoder(new PasswordEncoder() {
@Override
public String encode(CharSequence charSequence) {
return ENCODER.encode(charSequence);
}
@Override
public boolean matches(CharSequence charSequence, String s) {
if ( !ENCODER.matches(charSequence,s)){
// log.info("{}","密码对不上");
}else {
// log.info("{}","密码OK");
}
return ENCODER.matches(charSequence,s);
}
});
}
}
