Shiro报错 No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util

Shiro 报错

1, error details

org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.  This is an invalid application configuration.
    at org.apache.shiro.SecurityUtils.getSecurityManager(SecurityUtils.java:123)
    at org.apache.shiro.subject.Subject$Builder.<init>(Subject.java:627)
    at org.apache.shiro.SecurityUtils.getSubject(SecurityUtils.java:56)

2, error scenario

Struts2 + Spring + Hibernate integration framework Shiro error.
UserAction login method given position in the class Subject subject = SecurityUtils.getSubject();.

3, the solution

①, check whether SecurityManager

There are two SecurityManager configuration, one is declared in the spring xml configuration file.

Another is to write Shiro configuration class, be declared using annotations

@Configuration
public class ShiroConfig {

	@Bean
	public ShiroFilterFactoryBean getBean(@Qualifier("securityManager") DefaultWebSecurityManager securityManager){
	    ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
	    bean.setSecurityManager(securityManager);
	    bean.setLoginUrl("/login.jsp");
	    Map<String,String> filterMap = new LinkedHashMap<>();
	    filterMap.put("/login","anon");
	    filterMap.put("/*","authc");
	    bean.setFilterChainDefinitionMap(filterMap);
	    return bean;
	}
	
	@Bean("securityManager")
	public DefaultWebSecurityManager getSecurityManage(@Qualifier("accountRealm")AccountRealm accountRealm){
	    DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
	    securityManager.setRealm(accountRealm);
	    return securityManager;
	}
	
	@Bean("accountRealm")
	public AccountRealm getAccountRealm(){
	    return new BosRealm();
	}
}

$\ Color {red} Note: only about the above configuration,$

$\ Color {red} Please be modified according to your project, not directly copy.$

$\color{red}两种方式配置一种即可！$

②、检查web.xml文件中是否添加shiro过滤器

③、检查web.xml文件中shiro过滤器申明顺序

$\color{red}如果你配置了SecurityManager、shiro过滤器，$

$\ Color {red} but still error!$

Turned over several hours. . .
The point is not to praise can not be resolved, / manual funny / manual funny!
