Spring boot 2.0 整合 Security JWT 前后分离 认证授权

Spring Security 简介

Spring Security 主要作用是认证与授权
Spring Security 和 jwt 相关的介绍自行百度吧

下面直接上代码,注意看注释 有相关的代码作用解释,如果有错误的地方,请指出 一起学习 谢谢!

MyInvocationSecurityMetadataSourceService 加载资源与权限的对应关系

/***
 *
 * @FileName: MyInvocationSecurityMetadataSourceService
 * @Company:
 * @author    
 * @Date      2018年05月11日
 * @version   1.0.0
 * @remark:   加载资源与权限的对应关系
 * @explain 实现FilterInvocationSecurityMetadataSource接口也是必须的。 首先,这里从数据库中获取信息。 其中loadResourceDefine方法不是必须的,
 *           这个只是加载所有的资源与权限的对应关系并缓存起来,避免每次获取权限都访问数据库(提高性能),然后getAttributes根据参数(被拦截url)返回权限集合。
 *           这种缓存的实现其实有一个缺点,因为loadResourceDefine方法是放在构造器上调用的,而这个类的实例化只在web服务器启动时调用一次,那就是说loadResourceDefine方法只会调用一次,
 *           如果资源和权限的对应关系在启动后发生了改变,那么缓存起来的权限数据就和实际授权数据不一致,那就会授权错误了。但如果资源和权限对应关系是不会改变的,这种方法性能会好很多。
 *           要想解决 权限数据的一致性 可以直接在getAttributes方法里面调用数据库操作获取权限数据,通过被拦截url获取数据库中的所有权限,封装成Collection返回就行了。(灵活、简单
 *
 *           器启动加载顺序:1:调用loadResourceDefine()方法  2:调用supports()方法   3:调用getAllConfigAttributes()方法

    @Override
    public boolean matches(HttpServletRequest request) {
        if (matchers.matches(request)) {
            return false;
        }
        return processingMatcher.matches(request) ? true : false;
    }
}

UrlMatcher url匹配接口

public interface UrlMatcher {
    Object compile(String paramString);
    boolean pathMatchesUrl(Object paramObject, String paramString);
    String getUniversalMatchPattern();
    boolean requiresLowerCaseUrl();
}

AntUrlPathMatcher url 匹配 在 MyInvocationSecurityMetadataSourceService 类中会用到

@Component
public class AntUrlPathMatcher implements UrlMatcher {
    private boolean requiresLowerCaseUrl;
    private PathMatcher pathMatcher;
    public AntUrlPathMatcher()   {
        this(true);

    }
    public AntUrlPathMatcher(boolean requiresLowerCaseUrl)
    {
        this.requiresLowerCaseUrl = true;
        this.pathMatcher = new AntPathMatcher();
        this.requiresLowerCaseUrl = requiresLowerCaseUrl;
    }

    public Object compile(String path) {
        if (this.requiresLowerCaseUrl) {
            return path.toLowerCase();
        }
        return path;
    }

    public void setRequiresLowerCaseUrl(boolean requiresLowerCaseUrl){

        this.requiresLowerCaseUrl = requiresLowerCaseUrl;
    }

    public boolean pathMatchesUrl(Object path, String url) {
        if (("/**".equals(path)) || ("**".equals(path))) {
            return true;
        }

        return this.pathMatcher.match((String)path, url);
    }

    public String getUniversalMatchPattern() {
        return"/**";
    }

    public boolean requiresLowerCaseUrl() {
        return this.requiresLowerCaseUrl;
    }

    public String toString() {
        return super.getClass().getName() + "[requiresLowerCase='"
                + this.requiresLowerCaseUrl + "']";
    }

前端使用ajax方式登录

 //登录页面登录按钮事件
    var handleSignInFormSubmit = function() {
        $('#m_login_signin_submit').click(function(e) {
            e.preventDefault();
            var btn = $(this);
            var form = $(this).closest('form');

            form.validate({
                rules: {
                    userAccount: {
                        required: true
                    },
                    userPwd: {
                        required: true
                    }
                },
                messages: {
                        userAccount: {
                                required: "请输入登录用户."
                        },
                        userPwd: {
                                required: "请输入登录密码."
                        }
                    }
            });

            if (!form.valid()) {
                return;
            }

            btn.addClass('m-loader m-loader--right m-loader--light').attr('disabled', true);

            form.ajaxSubmit({
                type: 'post',
                url: ajaxUrl+'login/entry',
                success: function(response, status, xhr, $form) {
                    console.log(response);
                    if(response.status != 0){
                        btn.removeClass('m-loader m-loader--right m-loader--light').attr('disabled', false);
                        showErrorMsg(form, 'danger', '错误的用户名或密码.');
                    }else {
                        //得到登录后的token
                        var access_token = response.data.access_token;
                        localStorage.setItem('user_token', JSON.stringify(access_token));
                        localStorage.setItem('user',  JSON.stringify(response.data));
                        window.location.href="assets/snippets/pages/home/index.html";
                    }
                },
                error:function (response, status, xhr) {
                    btn.removeClass('m-loader m-loader--right m-loader--light').attr('disabled', false);
                    showErrorMsg(form, 'danger', '网络出现错误.');
                }
            });
            return false; // 阻止表单自动提交事件,必须返回false,否则表单会自己再做一次提交操作,并且页面跳转
        });
    }

携带token信息请求其它接口获取数据(以删除为例)

  var userToken = JSON.parse(localStorage.getItem('user_token'));

  $.ajax({
                url: ajaxUrl+'userRole/del',
                data : {
                    roleId:checkboxRoleId,
                    userIds:selectDeleteUserIds.toString(),
                    _method: 'DELETE'
                },
                type:"POST",
                dataType:"json",
                headers: {'Authorization': userToken},  //携带token到后台的方式
                success: function(response, status, xhr) {
                    var serverStatus = response.status;
                    toastr.clear();
                    //这里根据后台返回的状态做相应的处理,后台会根据token去校验权限,并返回相应的响应
                    if(serverStatus == -1){  
                        //登陆超时,需要重新登陆系统
                        toastr.error(response.message);
                        toastr.info("即将跳转到登陆页面.");
                        window.location.href="../../../../login.html";
                    }else  if (response.status != 0){
                        // 我设置的 response.status == 0 表示成功
                       //  response.status != 0 有可能是 无权限访问、token错误、登录失效等 根据后台认证返回 
                        toastr.error(response.message);
                    }else {
                        reloadUserGrid();
                    }
                    //移除遮罩层
                    mApp.unblock('#be-authorized-userGrid');
                },
                error:function (response, status, xhr) {
                    toastr.error("网络出现错误.");
                }
            });
