Shiro集成web环境[Springboot]-基础使用

Shiro集成web环境[Springboot]

1.shiro官网查找依赖的jar,其中shiro-ehcache做授权缓存时使用，另外还需要导入ehcache的jar包

        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-ehcache</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.3.2</version>
        </dependency>

<!-- https://mvnrepository.com/artifact/org.ehcache/ehcache -->
<dependency>
    <groupId>org.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>3.6.3</version>
</dependency>

过滤器依赖的层级关系：

2.配置shrio的核心过滤器

@Configuration
public class ShiroFilter {

    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(SecurityManager securityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //shiro会对所有资源进行控制,默认不拦截  需要配置
        Map<String,String> map = new HashMap<>();
        //多个过滤器  AnonymousFilter  匿名过滤器   简称anon
        // FormAuthenticationFilter  认证过滤器     简称authc
        map.put("/**","authc");
        //多个过滤器组成过滤器链
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        //设置认证页面路径
        shiroFilterFactoryBean.setLoginUrl("/main/login.jsp");
        return shiroFilterFactoryBean;
    }

    @Bean
    public SecurityManager getSecurityManager(){
        //web环境下securityManage的实现类为DefaultWebSecurityManager
        SecurityManager securityManager = new DefaultWebSecurityManager();
        return securityManager;
    }
}

其中shiro过滤器中的SecurityManager 属性必须设置，否则报错如下：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getShiroFilterFactoryBean': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanInitializationException: SecurityManager property must be set.

注入方式：

1. new SecurityManager 后set赋值给ShiroFilter 不推荐
2. 自动注入，自动注入前应该考虑该类是否由spring工厂管理？没有管理 交由spring工厂管理
3. 自动注入只在一个方法中使用 无需自动注入，java配置形式提供了方法形参的注入，该形参是基于类型的注入，凡是由spring工厂管理的类，所需的方法形参类型都可以由spring工厂提供

如图关系：

测试1：设置认证过滤器，访问index.jsp 无法到达且视图解析指向login.jsp 说明该请求没有经过认证

测试2：设置匿名过滤器，访问index.jsp可到到
