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。
