要在Spring Boot项目中集成Apache Shiro框架,可以按照以下步骤进行操作:
pom.xml
文件中添加Shiro和Spring Boot Shiro相关的依赖。例如:<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring-boot-starter</artifactId>
<version>1.7.1</version>
</dependency>
ShiroConfig.java
,并使用@Configuration
注解进行标注。在这个类中,你可以配置Shiro的各种组件,如SecurityManager
、Realm
、Filter
等。例如:@Configuration
public class ShiroConfig {
@Bean
public SecurityManager securityManager(CustomRealm customRealm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(customRealm);
return securityManager;
}
@Bean
public CustomRealm customRealm() {
return new CustomRealm();
}
@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager);
// 配置过滤器链
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
filterChainDefinitionMap.put("/admin/**", "authc");
filterChainDefinitionMap.put("/**", "anon");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;
}
}
在上面的示例中,CustomRealm
是一个自定义的Realm类,用于处理身份验证和授权逻辑。ShiroFilterFactoryBean
用于配置过滤器链,定义了哪些URL需要认证和授权。
org.apache.shiro.realm.AuthorizingRealm
接口,创建一个自定义的Realm类。在这个类中,你可以实现doGetAuthenticationInfo
和doGetAuthorizationInfo
方法,分别用于处理身份验证和授权逻辑。例如:public class CustomRealm extends AuthorizingRealm {
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
// 获取用户名和密码
String username = (String) token.getPrincipal();
String password = new String((char[]) token.getCredentials());
// 查询用户信息
User user = userService.findByUsername(username);
if (user == null || !user.getPassword().equals(password)) {
throw new UnknownAccountException("用户名或密码错误");
}
return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), getName());
}
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 获取用户角色和权限
String username = (String) principals.getPrimaryPrincipal();
User user = userService.findByUsername(username);
List<String> roles = user.getRoles();
List<String> permissions = user.getPermissions();
// 创建授权信息对象
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
authorizationInfo.setRoles(roles);
authorizationInfo.setStringPermissions(permissions);
return authorizationInfo;
}
}
在上面的示例中,userService
是一个自定义的服务类,用于查询用户信息。
@EnableShiro
注解,以启用Shiro集成。例如:@SpringBootApplication
@EnableShiro
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
完成以上步骤后,你的Spring Boot项目就成功集成了Apache Shiro框架,并可以进行身份验证和授权操作了。你可以根据具体需求对Shiro进行进一步的配置和扩展。
