在一个spring boot项目中，需要防止CSRF攻击，按理说应该集成spring security才对。
但是不想使工程变得太复杂，这时可以只把spring security中的相关filter引入来进行。
在pom中添加相关依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<!-- Security (used for CSRF protection only) -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
</dependency>
</dependencies>
在app启动时,添加CsrfFilter
@SpringBootApplication
public class Application extends WebMvcConfigurerAdapter {
@Bean
public FilterRegistrationBean csrfFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new CsrfFilter(new HttpSessionCsrfTokenRepository()));
registration.addUrlPatterns("/*");
return registration;
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
form中添加CSRF的hidden字段
<input name="${(_csrf.parameterName)!}" value="${(_csrf.token)!}" type="hidden">
ajax中添加CSRF的头
xhr.setRequestHeader("${_csrf.headerName}", "${_csrf.token}");
