基于Web(GUI)的多租户工作流平台

使用Spring Boot和AngularJS框架构建Web应用程序。创建多租户模型，使每个组织都能够访问自己的工作流。在服务器端使用Spring Security进行身份验证和授权，确保每个用户只能访问其授权的工作流程。在前端使用AngularJS创建用户界面，使用户能够创建、编辑和管理他们的工作流。

示例代码：

服务器端：

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private DataSource dataSource;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/admin/**").hasRole("ADMIN")
            .antMatchers("/user/**").hasAnyRole("ADMIN", "USER")
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .and()
            .logout().logoutSuccessUrl("/");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.jdbcAuthentication().dataSource(dataSource)
            .usersByUsernameQuery("SELECT username, password, enabled FROM users WHERE username=?")
            .authoritiesByUsernameQuery("SELECT username, role FROM user_roles WHERE username=?")
            .passwordEncoder(passwordEncoder());
    }

    private PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

前端：

var app = angular.module('workflowApp', []);

app.controller('WorkflowCtrl', function($scope, $http) {
    $http.get('/api/workflows')
        .then(function(response) {
            $scope.workflows = response.data;
        });

    $scope.addWorkflow = function() {
        $http.post('/api/workflows', $scope.newWorkflow)
            .then(function(response) {
                $scope.workflows.push(response.data);
                $$scope.newWorkflow = {};
            });
    };

    $scope.editWorkflow = function(workflow) {
        $http.put('/api/workflows/' + workflow.id, workflow);
    };

    $scope.deleteWorkflow = function(workflow) {
        $http.delete('/api/workflows/' + workflow.id)
            .then(function() {
                var index = $scope.workflows.indexOf(workflow);
                $scope.workflows.splice(index, 1);
            });
    };
});
