SpringBoot is integrated with shiro and the problem that @ Autowired cannot be injected into Service in MyRealm

There are many problems on the Internet, such as Spring loading sequence and shiroFilter before Spring automatically assembles bean. In fact, it is possible to ignore the following low-level errors.

In ShiroConfiguration, use @ Bean to inject MyRealm into ApplicationContext, not new objects directly.

Reason and call Service1 in Controller, if it is SpringBean, it cannot be new by itself.

Wrong way:

@Bean(name = "securityManager")
public SecurityManager securityManager() {
    DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
    MyRealm myRealm = new MyRealm();
    manager.setRealm(myRealm);
    return manager;
  }

Correct way:

@Bean(name = "myRealm")
public MyRealm myAuthRealm() {
    MyRealm myRealm = new MyRealm();
    return myRealm;
  }
@Bean(name = "securityManager")
public SecurityManager securityManager(@Qualifier("myRealm")MyRealm myRealm) {
    DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
    manager.setRealm(myRealm);
    return manager;
  }
