  • 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):

    复制代码
    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">
    

    }

    复制代码

      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

    }</br>
    

    }

    复制代码

      Function实体(权限):

    复制代码
    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>
    

    }

    复制代码

      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:

    复制代码
    /**
         * 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>

                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>
    
    复制代码

      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

    复制代码
    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 com.cy.coo.service.UserService;

      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。

      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。
    复制代码
    @Configuration
    public class HibernateConfig {
    @Bean
    public FilterRegistrationBean registerOpenEntityManagerInViewFilterBean() {
    FilterRegistrationBean registrationBean
    = new FilterRegistrationBean();
    OpenEntityManagerInViewFilter filter
    = new OpenEntityManagerInViewFilter();
    registrationBean.setFilter(filter);
    registrationBean.setOrder(
    5);
    return registrationBean;
    }
    }
    复制代码

    参考文章:

    http://www.jianshu.com/p/a827ecdda99f

    http://www.w_2bc.com/article/201653 /*这个链接博客园不让我发啊,把w_2_b_c中的下划线删了即可*/

    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。
