基于RBAC的权限实战（1）——系统框架搭建

其他 2018-07-31 23:40:23 阅读次数: 0

很早之前就想写一个基于权限管理的项目，但是奈何技术有限，再加上对于前端技术实在是所知有限，所以最终就是无奈的放弃，最近没事儿的时候，看了一些相关的视频，这才是有了这个项目的出现，虽然说整个项目，都是完全从视频学来的，但是对于我来说，却是让我了解到了RBAC权限相关的内容。具体的内容请自行百度或者谷歌去了解，这里我们就不说了，现在直接开始搭建我们的权限项目RBAC。

1、新建maven的web项目RBAC。

 2、在pom文件中添加依赖：

<dependencies>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
        </dependency>

特此说明，因为我本地的mysql安装的是8.0的版本，所以mysql的jar包用的是8.0.11的版本的。

3、在src/main/resources目录下增加以下配置文件：

 具体内容如下：

3.1）jdbc.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/power?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC
jdbc.username=root
jdbc.password=123456

3.2）config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <typeAliases>

    </typeAliases>
</configuration>

3.3）spring-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </property>
    </bean>

    <!-- 增加对于dao层的扫描路径 -->

    <aop:config>
        <aop:advisor advice-ref="transactionAdvice" pointcut="execution(* com.yukio..*Service.*(..))" />
    </aop:config>
</beans>

3.4）springmvc-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

    <!-- spring mvc 增加对controller的注释 -->
    <context:component-scan base-package="com.yukio.*" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>


    <!-- 增加对静态资源不进行拦截的配置 -->
    <mvc:default-servlet-handler />
    <mvc:annotation-driven />

    <!-- 增加视图解析器 必须要放置到最后一个(因为允许多个视图解析器的存在s) -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />

        <property name="maxUploadSize" value="2097152" />
        <property name="resolveLazily" value="true" />
    </bean>


</beans>

4、在web.xml中添加相应的启动内容：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">


    <!-- spring的配置 start -->
    <!-- 扫描文件路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:spring/spring-*.xml</param-value>
    </context-param>

    <!-- 监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- spring的配置 end -->

    <!-- 配置编码过滤器 start -->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encoding</filter-name>
        <servlet-name>springmvc</servlet-name>
    </filter-mapping>

    <!-- 配置编码过滤器 end -->

    <!-- springmvc的配置 start -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- springmvc的配置 end -->

</web-app>

5、新建数据库表t_user:

DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(10) COLLATE utf8_bin DEFAULT NULL,
  `loginacct` varchar(12) COLLATE utf8_bin DEFAULT NULL,
  `userpswd` varchar(50) COLLATE utf8_bin DEFAULT NULL,
  `email` varchar(20) COLLATE utf8_bin DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

6、新建实体类User.java

package com.yukio.rbac.bean;

public class User {

    private Integer id;

    private String username;

    private String loginacct;

    private String userpswd;

    private String email;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getLoginacct() {
        return loginacct;
    }

    public void setLoginacct(String loginacct) {
        this.loginacct = loginacct;
    }

    public String getUserpswd() {
        return userpswd;
    }

    public void setUserpswd(String userpswd) {
        this.userpswd = userpswd;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", username=" + username + ", loginacct=" + loginacct + ", userpswd=" + userpswd
                + ", email=" + email + "]";
    }

}

7、新建UserDao.java

package com.yukio.rbac.dao;

import java.util.List;

import org.apache.ibatis.annotations.Select;

import com.yukio.rbac.bean.User;

public interface UserDao {

    @Select("select *  from t_user")
    public List<User> queryAll();

}

8、新建业务类UserService.java以及UserServiceImpl.java

package com.yukio.rbac.service;

import java.util.List;

import com.yukio.rbac.bean.User;

public interface UserService {

    public List<User> queryAll();

}
package com.yukio.rbac.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.yukio.rbac.bean.User;
import com.yukio.rbac.dao.UserDao;
import com.yukio.rbac.service.UserService;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    public List<User> queryAll() {

        return userDao.queryAll();
    }

}

9、新建控制器类TestController.java

package com.yukio.rbac.controller;

import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.yukio.rbac.bean.User;
import com.yukio.rbac.service.UserService;

@Controller
@RequestMapping("/test")
public class TestController {

    @Autowired
    private UserService userService;

    @ResponseBody
    @RequestMapping("/queryAll")
    public Object queryAll() {

        List<User> list = userService.queryAll();

        return list;

    }
}

10、启动环境，在浏览器输入http://localhost:8080/RBAC/test/queryAll，结果如下所示：

11、userDao为一个代理对象，也能够看到配置的事物已经OK

 

好了，RBAC项目的基本框架已经是搭建起来了，接下来一篇将会完成系统的登录。因为最近有点儿忙，所以相关的mybatis学习和下一篇，同样都会放到双休日来进行更新。
