SpringMvc-Httl-shiro的整合

来到新的公司一个月，以前实习公司的用的是srping+hibernate+struts2,而在这里不在用的这些了，而是用的springMVC和jdbc模板来操作数据了，所以又用了一段时间去慢慢融入这个新的体系中去；但终究这些技术是万变不离其宗的，学习也是很快的事，所以我也就很快的就融入了这个团队；

进入正题吧！我这里其实就是想把学习新东西自己记录下来，这有助于我的学习也有助于大家的学习;把springmvc+httl+shiro+maven给整合起来;我刚来到新公司这里已经是搭建好了这个项目；所以我也在空闲时间之余把这些知识给过了一遍，也有助于我开发效率的提高；

我使用的开发工具室MyEclipse(开发工具的使用都是大同小异)；

至于httl和shiro的优势我就不多说了有兴趣的看：

废话不多说，开始搭建吧。。。

1：首先建立一个javaweb项目

2：配置pom.xml导入必须的jar包

        <!--当你运行的环境是jre是时;httl模板必须加入这个jar包；还有就是必须在httl的 httl.properties注入属性值：
        compiler=httl.spi.compilers.JavassistCompiler。。这点很重要,不然当你启动tomcat时会一直抛classnotfound异常-->

3：修改web.xml文件

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

        <param-value>

        </param-value>
    </context-param>
    <!-- 配置Shiro过滤器,先让Shiro过滤系统接收到的请求 -->

    <!-- 使用[/*]匹配所有请求,保证所有的可控请求都经过Shiro的过滤 -->

    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <init-param>
            <!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>

    </filter-mapping>

    <!-- Spring MVC Servlet 载入 -->

    </listener>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

4：添加httl.properties文件

import.packages+=com.lishun.controller

template.directory=/WEB-INF/templates

template.suffix=.httl

input.encoding=utf-8

output.encoding=utf-8

reloadable=true

precompiled=true

compiler=httl.spi.compilers.JavassistCompiler

import.methods+=com.lishun.httl.staticMethods.ShiroKit

注:import.packages：领域模型包导入

import.methods:这里可以封装在httl模板页面上使用的静态方法

template.directory：模板文件目录；

template.suffix：模板文件后缀

input.encoding：资源加载编码

output.encoding: 模板输出编码

precompiled:是否预编译

reloadable: 是否热加载;开发模式下建议开启

compiler：（摘自httl官网）

用于将模板类编译成字节码，缺省使用根据JDK版本自适应编译器：(缺省值不用配)

1	compiler=httl.spi.compilers.AdaptiveCompiler

当前运行环境为JDK1.6以前版本时，AdaptiveCompiler将适配到JavassistCompiler，否则将适配到JdkCompiler。

你可以强制指定使用jdk自带的编译器：(必需要用JDK运行，JRE不行，JDK比JRE多编译工具包)

1	compiler=httl.spi.compilers.JdkCompiler

你也可以换成javassist编译：(如果为JRE运行，请使用javassist编译)

1	compiler=httl.spi.compilers.JavassistCompiler

当然，也就需要增加javassist的jar包依赖：

javassist-3.15.0-GA.jar

<dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.15.0-GA</version> </dependency>

5:编写applicationContext-shiro.xml 注：该文件是管理shiro的

<!-- 这里别忘了配置，否则会导致自定义的Realm的属性值无法注入 -->
    <context:component-scan base-package="com.lishun"></context:component-scan>
    <!-- 继承自AuthorizingRealm的自定义Realm,即指定Shiro验证用户登录的类为自定义的UserRealm.java -->
     <bean id="shiroRealm" class="com.lishun.shiro.realm.UserRealm" >

     </bean> 

    <!-- 基于Form表单的身份验证过滤器 -->
    <bean id="formAuthenticationFilter"
        class="org.apache.shiro.web.filter.authc.FormAuthenticationFilter">
        <property name="usernameParam" value="username" />
        <property name="passwordParam" value="password" />
        <property name="loginUrl" value="/users/index.html" />
        <property name="successUrl" value="/index/index.html" />
    </bean>
    <context:component-scan base-package="com.lishun"></context:component-scan>
    <bean
        class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
        depends-on="lifecycleBeanPostProcessor">
        <property name="proxyTargetClass" value="true" />
    </bean>

    <!-- 这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替 -->
    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realm" ref="shiroRealm" />
    </bean>
    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <!-- 调用自定义的权限管理器 -->
        <property name="securityManager" ref="securityManager" />

        <!-- 配置登陆成功后跳转地址 -->
        <property name="successUrl" value="/index/index" />

        <!-- 配置登陆时请求的地址 -->
        <property name="loginUrl" value="/users/index" />

        <!-- 如果请求的资源不再你的权限范围内，则跳转到error.htm -->
        <property name="unauthorizedUrl" value="/users/noAuth" />

        <property name="filters">
            <map>
                <entry key="authc" value-ref="formAuthenticationFilter"></entry>
            </map>
        </property>
        <property name="filterChainDefinitions">
            <value>
                <!-- anon表示此地址不需要任何权限即可访问 -->
                /users/*=anon
                <!--login页面和logout页面不需要验证 -->
                /login* = anon
                <!--访问所有文件,authc必须通过验证后才能访问 -->
                /** = authc
            </value>
        </property>
    </bean>

    <!-- 相当于调用SecurityUtils.setSecurityManager(securityManager) -->
    <bean
        class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="staticMethod"
            value="org.apache.shiro.SecurityUtils.setSecurityManager" />
        <property name="arguments" ref="securityManager" />
    </bean>
    <!-- Shiro生命周期处理器 -->
    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />

6.编写spring-mvc.xml文件 注:该文件是管理springmvc的

<!-- 自动扫描且只扫描@Controller -->
    <context:component-scan base-package="com.lishun"
        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>

    <!-- 启用SpringMVC的注解功能,它会自动注册HandlerMapping、HandlerAdapter、ExceptionResolver的相关实例 -->
    <mvc:annotation-driven />

    <!-- 配置SpringMVC的视图解析器 httl视图 -->
    <bean id="viewResolver" class="httl.web.springmvc.HttlViewResolver">
        <property name="contentType" value="text/html; charset=UTF-8" />
    </bean>

    <!-- 在spring-mvc.xml配置文件添加Shiro Spring AOP权限注解的支持： -->
    <aop:config proxy-target-class="true"></aop:config>
    <bean
        class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
        <property name="securityManager" ref="securityManager" />
    </bean>
    <!-- 当前用户没有权限时跳转到的页面： -->
    <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <props>
                <prop key="org.apache.shiro.authz.UnauthorizedException">/users/unauthorizedView</prop>
            </props>
        </property>
    </bean>

7：编写用户实体（User）和角色实体（Role）

public class User {
    private String name;
    private String password;
    private Role role;
    @Override
    public String toString() {
        return "User [name=" + name + ", password=" + password + ", role="
                + role + "]";
    }
    public String getName() {
        return name;
    }
    public User() {
        super();
    }
    public void setName(String name) {
        this.name = name;
    }
    public User(String name, String password) {
        super();
        this.name = name;
        this.password = password;
    }
    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Role getRole() {
        return role;
    }

    public void setRole(Role role) {
        this.role = role;
    }
}
---------------------------------------------------分割线

public class Role {
    private String roleName;
    private Set<String> rolePermissions;
    public Set<String> getRolePermissions() {
        return rolePermissions;
    }
    public void setRolePermissions(Set<String> rolePermissions) {
        this.rolePermissions = rolePermissions;
    }
    public String getRoleName() {
        return roleName;
    }
    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }
}

8：在httl模板上执行静态函数的类

/*
 * 在httl模板上可以直接使用的函数
 */
public class ShiroKit {
    /**
     * 禁止初始化
     */
    private ShiroKit() {
    }
    /**
     * 获取 Subject
     *
     * @return Subject
     */
    protected static Subject getSubject() {
        return SecurityUtils.getSubject();
    }
    /**
     * 验证当前用户是否拥有指定权限,使用时与lacksPermission 搭配使用
     *
     * @param permission
     *            权限名
     * @return 拥有权限：true，否则false
     */
    public static boolean hasPermission(String permission) {
        boolean ret = getSubject() != null && permission != null && permission.length() > 0 && getSubject().isPermitted(permission);
        return ret;
    }

    /**
     * 与hasPermission标签逻辑相反，当前用户没有制定权限时，验证通过。
     *
     * @param permission
     *            权限名
     * @return 拥有权限：true，否则false
     */
    public static boolean lacksPermission(String permission) {
        return !hasPermission(permission);
    }

}

9：自定义用户验证规则(必须继承AuthorizingRealm)

public class UserRealm extends AuthorizingRealm {

    @Autowired
    @Qualifier("userDao")
    private UserDao userDao;

    /*
     * 权限认证
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(
            PrincipalCollection principals) {
        // 根据用户配置用户与权限
        if (principals == null) {
            throw new AuthorizationException(
                    "PrincipalCollection method argument cannot be null.");
        }
        String name = (String) getAvailablePrincipal(principals);
        List<String> roles = new ArrayList<String>();
        User user = userDao.getUserByName(name);
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        // 把当前用户的角色保存到Subject中
        roles.add(user.getRole().getRoleName());
        info.addRoles(roles);
        // 把当前用户的权限保存到Subject中
        info.setStringPermissions(user.getRole().getRolePermissions());
        return info;
    }

    /*
     * 登陆认证
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(
            AuthenticationToken authcToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
        //获取页面输入用户名
        String username=(String) token.getPrincipal();
        //从dao层获取该用户
        System.out.println(userDao);
        User user = userDao.getUserByName(username);
        if (user == null) {
            throw new AuthorizationException();
        }

        SimpleAuthenticationInfo info = null;
        //存储令牌信息
        if (user.getName().equals(token.getUsername())) {
            info = new SimpleAuthenticationInfo(user.getName(),
                    user.getPassword(), getName());
        }
        return info;
    }

}

10：编写dao层

/*
 * 这里我就不查询数据数据了，侧重点不在这里，所以写死用户数据
 */
public class UserDao {

    private static List<User> list=new ArrayList<User>();
    private static Set<String> userPermissions=new HashSet<String>();
    private static Set<String> adminPermissions=new HashSet<String>();
    static {
        //lishun普通用户
        User lishun =new User();
        lishun.setName("lishun");
        lishun.setPassword("123");
        Role lishunRole=new Role();
        lishunRole.setRoleName("user");
        //lishun普通用户只拥有一个权限
        userPermissions.add("user:lishun:view");
        lishunRole.setRolePermissions(userPermissions);
        lishun.setRole(lishunRole);

        //admin超级用户
        User admin =new User();
        admin.setName("admin");
        admin.setPassword("123");
        Role adminRole=new Role();
        adminRole.setRoleName("admin");
        //admin用户拥有所有权限
        adminPermissions.add("user:lishun:view");
        adminPermissions.add("manager:lishun:view");
        adminRole.setRolePermissions(adminPermissions);
        admin.setRole(adminRole);
        list.add(admin);
        list.add(lishun);
    }
    public User getUserByName(String name){
        for (User u : list) {
            if(u.getName().equals(name)){
                return u;
            }
        }
        return null;
    }

11：编写控制器：用户登陆控制器

//不用任何权限都可以访问该控制器的方法
@Controller
public class UserController {

    /*
     * 登陆页面
     */
    @RequestMapping(value = "users/index", method = RequestMethod.GET)
    public String index() {

        return "users/login";
    }
    /*
     * 验证用户
     */
    @RequestMapping(value = "users/login", method = RequestMethod.POST)
    public String login(String username,String password,Model model){
        //获取到当前用户的的Subject及创建用户名/密码身份验证Token（即用户身份/凭证）
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);

        String error = null;
        try {
            //验证登陆
            subject.login(token);
        } catch (AuthenticationException e) {
            error = "warning message:Login failed,please check your username and password";
            model.addAttribute("errorMessage", error);
        }

    /*

<!--#set(String msg="httl模板测试") -->
<!--#set(String manageHost = request.getScheme()+"://"+request.serverName+":"+"a".valueOf(request.serverPort)+request.getContextPath())-->

<html>
<body>
    <form action="${manageHost}/users/login" method="post">
        <label style="color: red">${errorMessage}</label>
        <table>
            <tr>

-----------------------分隔符

至于httl的语法大家可以去官网上浏览,我这里就不多说，http://httl.github.io/zh/syntax.html

打开url：http://localhost:8080/SpringMvc-Httl-shiro/users/login

就可以浏览了

13 编写控制器：用户主页控制器

@Controller
public class IndexController {

    /*
     * 普通用户就可以访问该页面
     */
    @RequiresPermissions("user:lishun:view")
    @RequestMapping(value = "index/index", method = RequestMethod.GET)
    public String index() {
        System.out.println(SecurityUtils.getSubject().isPermitted("user:lishun:view"));
        return "index/index";
    }
}
-------------------------------------------分割线

用户主页模板index.httl

<!--#set(String msg="httl模板测试") -->
<!--#set(String manageHost = request.getScheme()+"://"+request.serverName+":"+"a".valueOf(request.serverPort)+request.getContextPath())-->

<html>
<body>
    #if(hasPermission("manager:lishun:view"))
        超级用户登陆
        <a href="${manageHost}/manager/user">管理用户</a>
    #else(hasPermission("user:lishun:view"))
        普通用户登陆
    #end
</body>
</html>

14 编写控制器：管理员控制器

@Controller
@RequestMapping("manager")
public class ManagerController {

    /*
     * 只有管理员才有权限查看本页面
     */
    @RequiresPermissions("manager:lishun:view")
    @RequestMapping(value = "/user", method = RequestMethod.GET)
    public String index() {

        return "manager/userManager";
    }

}
-------------------------------------------分割线

管理用户模板userManager.httl

<!--#set(String msg="httl模板测试") -->
<!--#set(String manageHost = request.getScheme()+"://"+request.serverName+":"+"a".valueOf(request.serverPort)+request.getContextPath())-->

<html>
<body>
    <h1>只有admin角色才可以访问</h1>
</body>
</html>

当你是普通用户访问该页面时因没有权限而跳转到无权限页面
