Shiro没有调用代码可访问的SecurityManager

Question

@Configuration
public class ShiroConfig {

    @Bean
    public Realm realm() {
        return new UserRealm();
    }

    @Bean
    public HashedCredentialsMatcher hashedCredentialsMatcher() {
        HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
        hashedCredentialsMatcher.setHashAlgorithmName(PasswordEncoder.getALGORITHM()); 
        hashedCredentialsMatcher.setHashIterations(PasswordEncoder.getITERATION()); 
        return hashedCredentialsMatcher;
    }

    @Bean
    public UserRealm shiroRealm() {
        UserRealm userRealm = new UserRealm();
        userRealm.setCredentialsMatcher(hashedCredentialsMatcher()); 
        return userRealm;
    }

    @Bean
    public SessionsSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(shiroRealm());
        return securityManager;
    }

    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        defaultAdvisorAutoProxyCreator.setUsePrefix(true);
        return defaultAdvisorAutoProxyCreator;
    }

    @Bean
    public ShiroFilterChainDefinition shiroFilterChainDefinition() {
        DefaultShiroFilterChainDefinition definition = new DefaultShiroFilterChainDefinition();
        definition.addPathDefinition("/login", "anon");
        definition.addPathDefinition("/register", "anon");
        definition.addPathDefinition("/api/**", "user");
        return definition;
    }
}

    @PostMapping("/login")
    @ResponseBody
    public Object login(@RequestParam("username") String username,
                        @RequestParam("password") String password) {
        if (username.equals("") || password.equals("")) {
            return "please provide complete information";
        }
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        Subject subject = SecurityUtils.getSubject(); // this line caused exception
        ...
    }

我对这个例外很困惑。有人能帮忙吗？

我使用的是Spring Boot 2.1.6。release和shiro-spring-boot-starter 1.4.0。

Answer 1

您是否使用shiro-spring-boot-web-starter依赖项而不是shiro-spring-boot-starter依赖项？

根据这个文档，看起来这是spring boot web应用程序所需要的。
