框架:前后端分离、Spring Boot + mybatis
1. 使用的是maven项目;在pom.xml 中加入依赖:
<!-- 预防XSS攻击工具 -->
<dependency>
<groupId>org.owasp.esapi</groupId>
<artifactId>esapi</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>
<groupId>org.jsoup</groupId>
<artifactId>jsoup</artifactId>
<version>1.9.2</version>
</dependency>
2. 在classpath下加入配置文件:validation.properties和ESAPI.properties

过滤器:在项目包下创建类 XssFilter实现Filter接口
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;

敏感字符转换类:HttpServletRequestWrapper

}
创建配置类:XSSFilterConfig
import mon.xssfilter.XssFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.servlet.Filter;
/**
* @author jxwen
* @create -10-19 9:14
* @desc
**/
@Configuration
public class XSSFilterConfig {
@Bean
public FilterRegistrationBean filterRegistrationBean() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(xssFilter());
registration.addUrlPatterns("/*");
registration.addInitParameter("paramName", "paramValue");
registration.setName("xssFilter");
return registration;
}
/**
* 创建一个bean
* @return
*/
@Bean(name = "xssFilter")
public Filter xssFilter() {
return new XssFilter();
}
}
配置完成, 架构如下:
END!!!!!!!
