基于SpringBoot实现用户身份验证工具
session失效时间
在Tomcat上,session的默认有效时间是30分钟。也可以通过配置文件修改session的有效时间。
1)修改web.xml
<!-- 设置session失效,单位分 --> <session-config> <session-timeout>1</session-timeout> </session-config>
2).yml文件
server.session.cookie.http-only= #是否开启HttpOnly server.session.timeout = #会话超时(秒)
使用过滤器获取session进行身份验证(未全部测试,慎用)
1)新建Filter
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.context.ApplicationContext; import org.springframework.stereotype.Component; import org.springframework.web.context.support.WebApplicationContextUtils; import javax.servlet.*; import javax.servlet.annotation.WebFilter; import javax.servlet.http.HttpServletRequest; import java.io.IOException; @Component @ServletComponentScan//让@WebFilter起作用 @WebFilter(urlPatterns = "/*") public class MyFilter implements Filter{ @Autowired private SessionKeyConfigProperties sessionKeyConfigProperties; @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest; System.out.println(sessionKeyConfigProperties.getUserTypeKey()); //通过session获取身份信息 AuthenticationUtil authenticationUtil = new AuthenticationUtil(sessionKeyConfigProperties); UserTypeEnum userType = authenticationUtil.getUserAuthentication(httpServletRequest.getSession()); //进行认证 //认证失败 if(userType == null){ //... } //用户不是管理员 if(userType != UserTypeEnum.ADMIN){ //... } filterChain.doFilter(servletRequest,servletResponse); } @Override public void destroy() { } }
细心的读者会发现我用了AuthenticationUtil,这是为了将读写用户身份认证信息的功能分离而设计的工具类 2)AuthenticationUtil类
import org.apache.shiro.web.session.HttpServletSession; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpSession; public class AuthenticationUtil { private SessionKeyConfigProperties configProperties; public AuthenticationUtil(SessionKeyConfigProperties configProperties) { this.configProperties = configProperties; } /** * 从session中获取用户的身份类型 * @param session * @return 身份类型 */ public UserTypeEnum getUserAuthentication(HttpSession session){ //获取session中的用户信息记录 Object userType = session.getAttribute(configProperties.getUserTypeKey()); //获取session中记录的用户类型 if(userType != null && userType instanceof UserTypeEnum) { return (UserTypeEnum)userType; } return null; } /** * 将用户的身份写入session中 * @param session * @param userType */ public void setUserAuthentication(HttpSession session,UserTypeEnum userType){ session.setAttribute(configProperties.getUserTypeKey(),userType); } }
3)配置文件SessiionKeyConfig.properties
user_type_key = userTypeKey
4)配置读取文件SessionKeyConfigProperties.class
import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Component; @Configuration @PropertySource("classpath:config/SessiionKeyConfig.properties") @Component public class SessionKeyConfigProperties { @Value("${user_type_key}") private String userTypeKey; public String getUserTypeKey() { return userTypeKey; } public void setUserTypeKey(String userTypeKey) { this.userTypeKey = userTypeKey; } }
5)Enum类
public enum UserTypeEnum { ADMIN, USER }
注:本文删除了一些package信息及部分import信息。Enum类和配置类的内容请根据项目需求及数据字典自行修改。
