The @ Configuration annotation can achieve the function of using xml configuration files in Spring

In the spring project, we integrate third-party frameworks such as shiro and configure them in the spring.xml configuration file, for example:

/ css/**=anon / js/**=anon / validatecode.jsp*=anon / images/**=anon / login.jsp=anon / service/**=anon / * * = authc

Integration with shiro at springboot:

@ Configurationpublic class ShiroConfig {@ Bean public ShiroFilterFactoryBean shirFilter (SecurityManager securityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean (); shiroFilterFactoryBean.setSecurityManager (securityManager); Map filterChainDefinitionMap = new HashMap (); shiroFilterFactoryBean.setLoginUrl ("/ login"); shiroFilterFactoryBean.setUnauthorizedUrl ("/ unauthc"); shiroFilterFactoryBean.setSuccessUrl ("/ home/index"); filterChainDefinitionMap.put ("/ *", "anon"); filterChainDefinitionMap.put ("/ authc/index", "authc"); return shiroFilterFactoryBean } @ Bean public HashedCredentialsMatcher hashedCredentialsMatcher () {HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher (); hashedCredentialsMatcher.setHashAlgorithmName (PasswordHelper.ALGORITHM_NAME); hashedCredentialsMatcher.setHashIterations (PasswordHelper.HASH_ITERATIONS); return hashedCredentialsMatcher;} @ Bean public EnceladusShiroRealm shiroRealm () {EnceladusShiroRealm shiroRealm = new EnceladusShiroRealm (); shiroRealm.setCredentialsMatcher (hashedCredentialsMatcher ()); return shiroRealm;} @ Bean public SecurityManager securityManager () {DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager (); securityManager.setRealm (shiroRealm ()); return securityManager @ Bean public PasswordHelper passwordHelper () {return new PasswordHelper ();}}

The @ Configuration annotation can achieve the effect of using xml configuration files in Spring.
