Maven+SpringMVC+MyBatis+Shiro整合開發

1.配置依賴:pom.xml

            </dependency>
  </dependencies>

  <build>
    <finalName>ZZUPrj</finalName>
  </build>
</project>

2.數據庫基本配置:db.properties

jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:mydb
jdbc.username=scott
jdbc.password=tiger

3.編寫自定義Realm

package cn.zzu.wcj.shiro.realm;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

import cn.zzu.wcj.entity.User;
import cn.zzu.wcj.service.IPermissionService;
import cn.zzu.wcj.service.IRoleService;
import cn.zzu.wcj.service.IUserService;

public class ShiroDbRealm extends AuthorizingRealm {

    @Autowired
    private IRoleService roleService   ;

    @Autowired
    private IPermissionService permissionService   ;

    @Autowired
    private IUserService userService   ;

    /**
     * 驗證權限時使用
     */
    @Override
    public AuthorizationInfo doGetAuthorizationInfo(
            PrincipalCollection principals) {
        SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
        String userName=(String)principals.getPrimaryPrincipal() ;    //得到用戶名
        try{
             info.addRoles(roleService.findByUserName(userName)); //根據用戶名查找全部角色名稱
             info.addStringPermissions(permissionService.findByUserName(userName));//根據用戶名查找全部權限
        }catch(Exception e){
             e.printStackTrace();
        }
        return info;
    }

    /**
     * 用戶登陸時使用
     */
    @Override
    public AuthenticationInfo doGetAuthenticationInfo(
            AuthenticationToken token) throws AuthenticationException {
        String userName=(String)token.getPrincipal();   //獲取用戶名
        AuthenticationInfo info=null   ;
        User user =null;
        try{
            user=this.userService.findByUserName(userName) ;   //根據用戶名查找到用戶
        }catch(Exception e){
            e.printStackTrace(); 
        }
        if(user !=null){
            info=new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"MyShiroDBRealm"); 
        }
        return info;
    }

}

4.配置applicationContext.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"

                  expression="org.springframework.web.bind.annotation.ControllerAdvice"/>         
     </context:component-scan>

    </bean>

    <!-- 配置註解事務 -->
    <bean id="transactionManager" 
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
          <property name="dataSource" ref="dataSource"></property>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>


    <!-- 配置Shiro -->
    <!-- 1.配置Realm -->
    <bean id="shiroDbRealm" class="cn.zzu.wcj.shiro.realm.ShiroDbRealm"></bean>

    <!-- 2.配置安全管理器 -->
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
       <property name="realm" ref="shiroDbRealm"></property>
    </bean>

    <!-- 3.配置Shiro過濾器 -->
    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <!-- 配置shiro安全接口 -->
        <property name="securityManager" ref="securityManager"></property>
        <!-- 配置身份認證失敗時跳轉的頁面 -->
        <property name="loginUrl" value="/login.jsp"></property>

    </bean>

    <!-- 4.配置Shiro內部lifecycle函數的bean執行 -->
    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor">
    </bean>

    <!-- 5.配置Shiro註解 -->
    <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" 
          depends-on="lifecycleBeanPostProcessor"/>  
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">  
        <property name="securityManager" ref="securityManager"/>  
    </bean> 

</beans>

5.配置SpringMVC:spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <!-- 配置自動掃描處理器 -->
    <context:component-scan base-package="cn.zzu.wcj" use-default-filters="false">
       <context:include-filter type="annotation" 
              expression="org.springframework.stereotype.Controller"/>
        <context:include-filter type="annotation" 
              expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
    </context:component-scan>


    <!-- 配置視圖解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>


    <!-- SpringMVC必備 -->
    <mvc:default-servlet-handler/>
    <mvc:annotation-driven></mvc:annotation-driven>

    <mvc:interceptors>
            <!-- 配置Token攔截器，防止用戶重複提交數據 -->
            <mvc:interceptor>
                <!--攔截所有得URL-->
                <mvc:mapping path="/**"/>
                <!--攔截器路徑-->
                <bean class="cn.zzu.wcj.interceptor.TokenInterceptor"/>

            </mvc:interceptor>
    </mvc:interceptors>

</beans>

6.簡單展示一下我登錄時編寫的表現層代碼

package cn.zzu.wcj.handler;

import javax.servlet.http.HttpServletRequest;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.zzu.wcj.entity.User;
import cn.zzu.wcj.service.IUserService;
import cn.zzu.wcj.util.EncryptUtils;

@RequestMapping("/UserHandler")
@Controller
public class UserHandler {


    @Autowired
    private EncryptUtils encryptUtils  ;

    @Autowired
    private IUserService userService   ;

    @RequestMapping("/login")
    public String login(User user,HttpServletRequest httpReq){
         String page="success"   ;   //默認頁面
         String userName=user.getUserName()  ;   //獲取用戶名
         String password=user.getPassword()  ;   //獲取密碼
         password=this.encryptUtils.encMD5(userName+"@{"+password+"}", "shiro") ;  //密碼加密處理
         user.setPassword(password);  //將用戶密碼修改爲加密後的密碼
         Subject currentUser=SecurityUtils.getSubject()  ;   //CurrentUser
         UsernamePasswordToken token=null ;
         token=new UsernamePasswordToken(userName, password)  ;   //創建令牌
         try{
            currentUser.login(token);    //登陸驗證
            this.userService.doLoginCheck(user)  ;   //重新設置設置登陸時間
         }catch(Exception e){
             httpReq.setAttribute("errMsg", "用戶名或密碼錯誤,請重新登陸!");   //設置錯誤信息
             page="redirect:/login.jsp"  ;
         }
         return page ;
    }

}

總結:在配置DBCP數據源的高級屬性時千萬別分散配置在db.properties,Eclipse每次都識別不了,我惱火死 了,不然會吃虧,好啦,框架都搭建完了,下面可以盡情的寫後臺代碼了
