SpringBoot+Spring security自定义登录校验

springboot项目中使用Spring security做安全管理，自定义校验方法。
1. 自定义WebSecurityConfig 继承WebSecurityConfigurerAdapter，重写configure方法，注入自定义校验bean
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
	//注入自定义校验类
    auth.authenticationProvider(daoAuthenticationProvider());
  }
  //配置策略
@Override
protected void configure(HttpSecurity http) throws Exception { //配置策略
    http.csrf().disable();
    http.authorizeRequests().
    		//不用做拦截的路径
            antMatchers("/static/**").permitAll().anyRequest().authenticated().
            //使用form表单提交
            and().formLogin()
            //登录页面，可以自定义
            .loginPage("/login").permitAll()
            //校验成功后执行
            .successHandler(loginSuccessHandler())
            .and().logout().permitAll().invalidateHttpSession(true)
            .logoutSuccessHandler(logoutSuccessHandler())
            .and().sessionManagement().maximumSessions(10).expiredUrl("/login")；
     //添加自定义拦截器       
	http.addFilterAt(adminKaptchaAuthenticationProcessingFilter(), 	UsernamePasswordAuthenticationFilter.class);
      
}
  //自定义校验类
DaoAuthenticationProvider daoAuthenticationProvider(){
    DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
    daoAuthenticationProvider.setUserDetailsService(springSecurityUserDetailsService);
    return daoAuthenticationProvider;
}
//注入自定义拦截器属性
private MacAuthenticationProcessingFilter adminKaptchaAuthenticationProcessingFilter(){
    MacAuthenticationProcessingFilter mac=  new MacAuthenticationProcessingFilter();
    mac.setAuthenticationManager(authenticationManagerBean());
    mac.setSpringSecurityUserDetailsService(springSecurityUserDetailsService);
    mac.setUsernameParameter("j_username");
    mac.setPasswordParameter("j_password");
    mac.setOsinfoParameter("j_pcosinfo");
    mac.setAuthenticationFailureHandler(adminExceptionMappingAuthenticationFailureHandler());
    mac.setAuthenticationSuccessHandler(adminSimpleUrlAuthenticationSuccessHandler());
    return mac;
}	

public SavedRequestAwareAuthenticationSuccessHandler adminSimpleUrlAuthenticationSuccessHandler(){
    SavedRequestAwareAuthenticationSuccessHandler save=  new SavedRequestAwareAuthenticationSuccessHandler();
    //登录成功后页面跳转页面
    save.setDefaultTargetUrl("/admin/index");
    save.setAlwaysUseDefaultTargetUrl(true);
    return save;
}

//错误类型，可以自定义
@Bean(name = {"adminExceptionMappingAuthenticationFailureHandler"})
public ExceptionMappingAuthenticationFailureHandler adminExceptionMappingAuthenticationFailureHandler(){
    ExceptionMappingAuthenticationFailureHandler ex=  new ExceptionMappingAuthenticationFailureHandler();
    Map failureUrlMap = new HashMap<>();
    failureUrlMap.put("org.springframework.security.core.userdetails.UsernameNotFoundException","/admin/login?error=1");//
    failureUrlMap.put("org.springframework.security.authentication.BadCredentialsException","/admin/login?error=2");//
    failureUrlMap.put("org.springframework.security.authentication.DisabledException","/admin/login?error=3");//
    failureUrlMap.put("com.lymatrix.springmvc.KaptchaException","/admin/login?error=4");//
    failureUrlMap.put("org.springframework.security.core.AuthenticationException","/admin/login?error=5");
    failureUrlMap.put("com.lymatrix.springmvc.MacException","/admin/login?error=6");//
    ex.setExceptionMappings(failureUrlMap);

    return ex;
}



/**
 *登录验证
 */
public class MacAuthenticationProcessingFilter extends UsernamePasswordAuthenticationFilter {
	....
	....
	//注入springSecurityUserDetailsService
	//重写验证方法
	@Override
	public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
		//如果是post请求
		if(request.getContentType().startsWith(MediaType.APPLICATION_JSON_VALUE)){

        	UserDetails userDetails = springSecurityUserDetailsService.loadUserByUsersn(usersn);
        	UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(
                userDetails.getUsername(), userDetails.getPassword());
       	 	setDetails(request, authRequest);
        	return this.getAuthenticationManager().authenticate(authRequest);
   		 }else{
   		 	//如果是form表单请求
   		 	.....
   		 	.....
   		 	request.getSession().setAttribute("LoginUserName", username);
        	return super.attemptAuthentication(request, response);

}

springSecurityUserDetailsService需要实现UserDetailsService

@Service("springSecurityUserDetailsService")
public class SpringSecurityUserDetailsService implements UserDetailsService {
	@Override
	public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
		if(!StringUtil.isNullOrEmpty(username)){
			User u = this.userService.getUserByName(username);
			if(u == null){ /** */
				int count = this.userService.getUserCount();
				if(count == 0){
					u = SystemInitialization.getVirtualAdminUser(username); 
				}
			}
			if(u != null){
				//查询用户权限相关操作
				Collection authorities = generateAuthorities(u);
				Collection authorities1 = getMenutree(u);
				authorities.addAll(authorities1);
				u.setAuthorities(new HashSet(authorities));
				return u;
			}
		
		}
	
		throw new UsernameNotFoundException("找不到参数[username="+username+"]指定的用户信息。");
	}
}

通过请求判断需要返回页面或者json

public class SavedRequestAwareAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {
	//核心方法
	@Override
	public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
        Authentication authentication) throws ServletException, IOException {	
			...
			...
		 if(request.getContentType().startsWith(MediaType.APPLICATION_JSON_VALUE)){
         	JSONObject res = new JSONObject();
            res.put("success",true);       
            res.put("msg","登录成功");       
            response.setStatus(200);     
            response.setContentType("application/json;charset=UTF-8");      
            response.getWriter().append(res.toString());
            response.getWriter().flush();         
         }
         ....
         ....
		String targetUrl = savedRequest.getRedirectUrl();
    	getRedirectStrategy().sendRedirect(request, response, targetUrl);
	}
}
