用户身份验证：基于SpringBoot的用户身份验证工具

1.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）

2.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 SessionK
ae19
eyConfigProperties 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
}
