SpringBoot 后台权限框架搭建（一）

项目名称定义为mountain（山）, 主要实现后端权限管理系统，包括用户管理、
角色管理、部门管理、菜单管理等。项目采用前后端分离模式开发，
后端使用springboot+shiro+mybatis+MySQL等；前端选用Element UI框架，
直接基于vue-element-admin的基础上扩展开发。

            return simpleAuthenticationInfo;
        }

    }
}

复制代码

注意点

ShiroConfig中配置shiro拦截器链，配置拦截和拦截的路径
在MyShiroRealm中添加角色权限和对应权限，并且添加用户认证。

如果添加了权限，例如下面MyShiroRealm中代码

//添加角色和权限
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
for (SysRole role : userInfo.getRoleList()) {
    //添加角色
    simpleAuthorizationInfo.addRole(role.getRoleName());
    for (SysMenu sysMenu : userInfo.getMenuList()) {
        //添加权限
        simpleAuthorizationInfo.addStringPermission(sysMenu.getPerms());
    }
}
复制代码

例如用户列表接口 sysuser/list 你添加了 userInfo:view 权限，那么你在controller这个接口上必须添加

@RequiresPermissions ,如下面代码：

@RequiresPermissions("userInfo:view")
@RequestMapping(value = "list", method = RequestMethod.POST)
@ResponseBody
public JSONObject findList(@RequestBody SysUser sysUser, HttpServletRequest request, HttpServletResponse response){
        ......
    }
复制代码

Mybatis相关配置

配置文件

在application.properties 配置文件中添加mybatis包扫描

mybatis.type-aliases-package=com.site.mountain.entity
复制代码

在springboot启动类上开启事务注解

@SpringBootApplication
@EnableTransactionManagement   //开启事物管理功能
public class MountainApplication {

    public static void main(String[] args) {
        SpringApplication.run(MountainApplication.class, args);
    }
}
复制代码

注意点

事务失效：springboot和shiro框架集成时，先加载shiro，这时sysUserService还没有实例化，导致事务失效，在sysUserService 上加载 @Lazy

配置多数据源

#配置监控统计拦截的filters，去掉后监控界面SQL无法进行统计，'wall'用于防火墙

注意点

数据源类中配置了Mybatis对应的Mapper.xml文件路径
MySQL 和Oracle对应配置文件中的配置的方式是不一样的，MySQL直接注解 @ConfigurationProperties(prefix = "spring.datasource.mysql") ,而Oracle是使用的

@Value("${oracle.datasource.url}")

配置日志

由于springboot2 默认引入logback相关的jar包，即下面的jar包中关联引用了

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.3.RELEASE</version>
</parent>
