  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):

  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:

Springboot+shiro配置笔记+错误小结(转)
/\*\*
\* 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

        </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></pre>
Springboot+shiro配置笔记+错误小结(转)

  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

}

Springboot+shiro配置笔记+错误小结(转)

  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。

Springboot+shiro配置笔记+错误小结(转)

  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。
Springboot+shiro配置笔记+错误小结(转)
@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:

Springboot+shiro配置笔记+错误小结(转)

 

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。
