为了防止XSS和SQL注入攻击，你可以使用Spring Boot的自动过滤器功能，并结合一些第三方库如Antisamy。
- 添加依赖到你的
pom.xml：
<!-- 用于XSS防护的库 -->
<dependency>
<groupId>org.owasp.antisamy</groupId>
<artifactId>antisamy</artifactId>
<version>1.5.12</version>
</dependency>- 配置XSS过滤器：
import org.owasp.validator.html.Policy;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.ContentNegotiatingViewResolver;
@Configuration
public class SecurityConfig {
@Autowired
private ContentNegotiatingViewResolver viewResolver;
@Bean
public Policy xssPolicy() {
// 加载XSS过滤策略
return Policy.getInstance("antisamy-slashdot.xml");
}
@Bean
public XssFilter xssFilter() {
// 创建XSS过滤器
return new XssFilter(xssPolicy());
}
@Bean
public FilterRegistrationBean xssFilterRegistration() {
FilterRegistrationBean registration = new FilterRegistrationBean(xssFilter());
registration.addUrlPatterns("/api/*"); // 设置过滤路径
registration.setOrder(1);
return registration;
}
}- 创建XSS过滤器类：
import org.springframework.stereotype.Component;
import org.owasp.validator.html.AntiSamy;
import org.owasp.validator.html.CleanResults;
import org.owasp.validator.html.Policy;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
@Component
public class XssFilter implements Filter {
private final Policy policy;
public XssFilter(Policy policy) {
this.policy = policy;
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
chain.doFilter(new XssHttpServletRequestWrapper((HttpServletRequest) request), response);
}
private static class XssHttpServletRequestWrapper extends HttpServletRequestWrapper {
private final HttpServletRequest request;
public XssHttpServletRequestWrapper(HttpServletRequest request) {
super(request);
this.request = request;
}
