Springboot+shiro配置笔记+错误小结

　　软件152 尹以操

　　springboot不像springmvc，它没有xml配置文件，那该如何配置shiro呢，其实也不难，用java代码+注解来解决这个问题。仅以此篇记录我对shiro的学习，如有对过客造成不便，实在抱歉！

　　一、加入jar包

　　既然要用到shiro，当然要加入它的jar包咯，在pom.xml中jar包依赖中加入：

        <dependency>

            <groupId>org.apache.shiro</groupId>

            <artifactId>shiro-spring</artifactId>

            <version>1.2.2</version>

        </dependency>

　　二、写实体类

　　这需要三个实体类，hibernate自动生成5个表

　　User实体（用户）：

package com.cy.coo.bean;
import java.util.List;


import javax.persistence.Column;


import javax.persistence.Entity;


import javax.persistence.FetchType;


import javax.persistence.GeneratedValue;


import javax.persistence.Id;


import javax.persistence.JoinColumn;


import javax.persistence.JoinTable;


import javax.persistence.ManyToMany;


import com.fasterxml.jackson.annotation.JsonBackReference;


@Entity


public class User {


@Id</br>
@GeneratedValue</br>
</span><span style="color: #0000ff">private</span> Integer user_id;<span style="color: #008000">//</span><span style="color: #008000">用户序号</span>

    


@Column(unique=true)


private String name;//账户


<span style="color: #0000ff">private</span> String password;<span style="color: #008000">//</span><span style="color: #008000">密码</span></br></br>

<span style="color: #0000ff">private</span> String salt;<span style="color: #008000">//</span><span style="color: #008000">盐</span></br></br>
    
<span style="color: #0000ff">private</span> Integer state;<span style="color: #008000">//</span><span style="color: #008000">用户状态</span></br></br>

<span style="color: #0000ff">private</span> String createtime;<span style="color: #008000">//</span><span style="color: #008000">创建时间</span>




@ManyToMany(fetch=FetchType.EAGER)//立即从数据库中进行加载数据;

@JoinTable(name="User_Role",joinColumns={@JoinColumn(name="user_id")},


inverseJoinColumns={@JoinColumn(name="role_id")})


private List<Role> roleList;


@JsonBackReference</br>
</span><span style="color: #0000ff">public</span> List&lt;Role&gt;<span style="color: #000000"> getRoleList(){</br>
    </span><span style="color: #0000ff">return</span><span style="color: #000000"> roleList;</br>
}</br></br>

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span> setRoleList(List&lt;Role&gt;<span style="color: #000000"> roleList){</br>
    </span><span style="color: #0000ff">this</span>.roleList=<span style="color: #000000">roleList;</br>
}</br>



注：其它getter和setter省略</span><span style="color: #000000">

}

　　关于为什么要在getRolelist这个方法上加上@JsonBackReference注解，可以查看这篇文章http://blog.csdn.net/maxu12345/article/details/45538157

　　Role实体（角色）：

package com.cy.coo.bean;

import java.io.Serializable;


import java.util.ArrayList;


import java.util.List;


import javax.persistence.Entity;


import javax.persistence.FetchType;


import javax.persistence.GeneratedValue;


import javax.persistence.Id;


import javax.persistence.JoinColumn;


import javax.persistence.JoinTable;


import javax.persistence.ManyToMany;


import com.fasterxml.jackson.annotation.JsonBackReference;


@Entity


public class Role implements Serializable {


private static final long serialVersionUID = 1L;

<span style="color: #0000ff">private</span> String role_name;<span style="color: #008000">//</span><span style="color: #008000">角色名称</span></br></br>

<span style="color: #0000ff">private</span> String role_description;<span style="color: #008000">//</span><span style="color: #008000">角色描述</span>




@ManyToMany


@JoinTable(name = "User_Role", joinColumns = { @JoinColumn(name = "role_id") }, inverseJoinColumns = {


@JoinColumn(name = "user_id") })


private List<User> userList=new ArrayList<>();

    </span><span style="color: #0000ff">this</span>.role_description =<span style="color: #000000"> role_description;</br>
}</br>

}

　　Function实体（权限）：

package com.cy.coo.bean;
import java.util.List;


import javax.persistence.Entity;


import javax.persistence.GeneratedValue;


import javax.persistence.Id;


import javax.persistence.JoinColumn;


import javax.persistence.JoinTable;


import javax.persistence.ManyToMany;





@Entity


public class Function {

@Id</br>
@GeneratedValue</br>
</span><span style="color: #0000ff">private</span> Integer function_id;<span style="color: #008000">//</span><span style="color: #008000">功能序号</span></br></br>

<span style="color: #0000ff">private</span> String permission;<span style="color: #008000">//</span><span style="color: #008000">权限字符串</span>

    


@ManyToMany</br>
@JoinTable(name </span>= "Role_Function", joinColumns = { @JoinColumn(name = "function_id") }, inverseJoinColumns =<span style="color: #000000"> {</br>
        @JoinColumn(name </span>= "role_id"<span style="color: #000000">) })</br>
</span><span style="color: #0000ff">private</span> List&lt;Role&gt;<span style="color: #000000"> roleList;</br></br>

</span><span style="color: #0000ff">public</span> List&lt;Role&gt;<span style="color: #000000"> getRoleList() {</br>
    </span><span style="color: #0000ff">return</span><span style="color: #000000"> roleList;</br>
}</br></br>

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span> setRoleList(List&lt;Role&gt;<span style="color: #000000"> roleList) {</br>
    </span><span style="color: #0000ff">this</span>.roleList =<span style="color: #000000"> roleList;</br>
}</br></br>

</span><span style="color: #0000ff">public</span><span style="color: #000000"> Integer getFunction_id() {</br>
    </span><span style="color: #0000ff">return</span><span style="color: #000000"> function_id;</br>
}</br></br>

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span><span style="color: #000000"> setFunction_id(Integer function_id) {</br>
    </span><span style="color: #0000ff">this</span>.function_id =<span style="color: #000000"> function_id;</br>
}</br></br></br>


</span><span style="color: #0000ff">public</span><span style="color: #000000"> String getPermission() {</br>
    </span><span style="color: #0000ff">return</span><span style="color: #000000"> permission;</br>
}</br>

</span><span style="color: #0000ff">public</span> <span style="color: #0000ff">void</span><span style="color: #000000"> setPermission(String permission) {</br>
    </span><span style="color: #0000ff">this</span>.permission =<span style="color: #000000"> permission;</br>
}</br>

}

　　这几个实体类的具体关系如下图，也完美的解释了为什么会生成5张表：

　　三、写一个与前端交互的controller方法，service层的具体逻辑的方法

    @PostMapping(value = "/logon")

    public Object logon(@RequestBody Login user) {


    </span><span style="color: #0000ff">return</span><span style="color: #000000"> userService.login(user);</br>
}</span></pre>

　　这个方法就是将前端传来的username和password封装到Login类中，Login类也只有这两个属性，然后调用Service层的login方法来处理。下面是service的login方法：

/**
     * 用户登录 create by yyc 2017年5月12日下午4:31:26
     */

    @Override

    public Object login(Login user) {

        String username = user.getUsername().trim();

        String password = user.getPassword().trim();


    </span><span style="color: #008000">//</span><span style="color: #008000"> 检查空值</span></br>
    <span style="color: #0000ff">if</span> (!<span style="color: #000000">CheckObjectField.CheckField(user)) {</br>
        </span><span style="color: #0000ff">throw</span> <span style="color: #0000ff">new</span> ResultException(CheckObjectField.FieldName + "为空！"<span style="color: #000000">);
    }</br>

    </span><span style="color: #008000">//</span><span style="color: #008000"> 检查用户状态</span></br>
    Integer userState =<span style="color: #000000"> userRepository.findUserState(username);</br>
    </span><span style="color: #0000ff">if</span> (<span style="color: #0000ff">new</span> Integer("1"<span style="color: #000000">).equals(userState)) {</br>
        </span><span style="color: #0000ff">throw</span> <span style="color: #0000ff">new</span> ResultException("该用户已锁定"<span style="color: #000000">);</br>
    }</br></br>

    </span><span style="color: #008000">//</span><span style="color: #008000"> 1、获取Subject实例对象</span></br>
    Subject currentUser =<span style="color: #000000"> SecurityUtils.getSubject();</br></br>

    </span><span style="color: #008000">//</span><span style="color: #008000"> 2、判断当前用户是否登录</span></br>
    <span style="color: #0000ff">if</span> (currentUser.isAuthenticated() == <span style="color: #0000ff">false</span><span style="color: #000000">) {</br>
        </span><span style="color: #008000">//</span><span style="color: #008000"> 3、将用户名和密码封装到UsernamePasswordToken</span></br>
        UsernamePasswordToken token = <span style="color: #0000ff">new</span><span style="color: #000000"> UsernamePasswordToken(username, password);</br></br>

        </span><span style="color: #008000">//</span><span style="color: #008000"> 4、认证</span></br>
        <span style="color: #0000ff">try</span><span style="color: #000000"> {</br>
            currentUser.login(token);</span><span style="color: #008000">//</span><span style="color: #008000"> 传到MyAuthorizingRealm类中的方法进行认证</span></br>
            Session session =<span style="color: #000000"> currentUser.getSession();</br>
            session.setAttribute(</span>"username"<span style="color: #000000">, username);</br>
        } </span><span style="color: #0000ff">catch</span><span style="color: #000000"> (AuthenticationException e) {</br>
            </span><span style="color: #0000ff">throw</span> <span style="color: #0000ff">new</span> ResultException("密码或用户名错误"<span style="color: #000000">);</br>
        }</br>
    }</br>
    </span><span style="color: #008000">//</span><span style="color: #008000"> 根据用户名查询角色信息</span></br>
    List&lt;String&gt; RoleNames =<span style="color: #000000"> roleService.findRoleName(username);</br></br>

    </span><span style="color: #0000ff">return</span> <span style="color: #0000ff">new</span><span style="color: #000000"> LoginReturn(username, RoleNames);</br></br>

}</span></pre>

　　service中主要是将用户名和密码封装到shiro的UsernamePasswordToken中，然后将token对象放到SecurityUtils.getSubject()的login方法中，以便shiro认证登录使用。认证失败就会抛出AuthenticationException这个异常，就对异常进行相应的操作，这里的处理是抛出一个自定义异常ResultException。

　　四、写我认为的shiro的核心类

package com.cy.coo.shiro;
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.authc.UsernamePasswordToken;


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.apache.shiro.util.ByteSource;


import org.slf4j.Logger;


import org.slf4j.LoggerFactory;


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


import com.cy.coo.bean.Function;


import com.cy.coo.bean.Role;


import com.cy.coo.bean.User;


import com.cy.coo.service.UserService;

//        //得到盐值加密后的密码：只用于方便数据库测试，后期不会用到。


//        Object md = new SimpleHash("MD5",upToken.getPassword(),salt,1024);


//        logger.info("盐值加密后的密码："+md);




info = new SimpleAuthenticationInfo(


user, //用户名


user.getPassword(), //密码


salt, //加密的盐值


getName()  //realm name


        );

return info;


}

}

　　这个类继承shiro的AuthorizingRealm ，主要有两个方法，一个是权限配置，一个是身份认证，权限配置：当我们要用到权限时shiro会回调doGetAuthorizationInfo这个方法，对当前的用户分配权限，这个方法中的嵌套for循环是怎么回事呢，其实就是将数据库中的对应角色、权限放进shiro中，让他来管理，这需要实体类User中有getRoleList()、getRole_name()和getFunctionList()、getPermission这几个方法，这几个个方法就是设计数据库和实体类时的东西了，关于shiro权限相关的实体类在前面已经给出了。身份认证：在用户登录认证的时候回调，认证失败就抛出AuthenticationException。

　　五、shiro配置类

　　这个没什么好说的，最后一个类是shiro的过滤器配置。可以看到我在每个方法上面加了一个@Bean(name="...")，其实这是spring的注解，将这个类放到spring容器中管理，在方法形参中使用@Qualifier(...)来使用它，以致于我们在方法体中调用某个方法时就方面多了。

在这里，关于shiro在springboot中的基础配置就完成了。下面是期间遇到的错误解决方案：

错误一：关于实体类的错误，springboot 中hibernate懒加载报错....................................No Session

解决方法：新建类配置OpenEntityManagerInViewFilter 以及上面角色类（表）和用户类（表）（Role、User）Role的红色字体也是必须的，及@ManyToMany(fetch=FetchType.EAGER)

由于博主基础的局限还不知道具体的原因是什么，但是解决了就好。

@Configuration
public class HibernateConfig {

           @Bean

           public FilterRegistrationBean registerOpenEntityManagerInViewFilterBean() {

               FilterRegistrationBean registrationBean = new FilterRegistrationBean();

               OpenEntityManagerInViewFilter filter = new OpenEntityManagerInViewFilter();

               registrationBean.setFilter(filter);

               registrationBean.setOrder(5);

               return registrationBean;

           }

}

错误二：这个在前面也提到过了，返回json数据出现Could not write JSON document: Infinite recursion（无法编写JSON文档：无限递归）；

在后面的使用中发现这个错误也是这样解决的，java.lang.IllegalStateException: Cannot call sendError() after the response has been committed，错误页面到最后就是这样，如图：

解决方法：

　　在controller返回数据到统一json转换的时候，出现了json infinite recursion stackoverflowerror的错误，即json在将对象转换为json格式的数据的时候，出现了无限递归调用的情况。

具体的情况如下：

A类中，有个属性：List<B> b， A与B的关系为 OneToMany；在B类中，有属性A a,引用到A中的字段id，并作为外键。hibernate查询结果正常，可以看到返回的A对象中，有b参数值，但在json转换的时候就出现了无限递归的情况。个人分析，应该是json在序列化A中的b属性的时候，找到了B类，然后序列化B类，而B类中有a属性，因此，为了序列化a属性，json又得去序列化A类，如此递归反复，造成该问题。

解决：

在B类中a的getter setter方法上加注解@JsonBackReference，其实自己试过只在getter方法上加@JsonBackReference也够了。
