无法在Spring Security中加载静态内容

标签: javascript java spring spring-boot spring-security

我从此来源构建了一个基本的spring身份验证服务: https://spring.io/guides/gs/securing-web/

试图使用stackoverflow上的几乎所有解决方案来包含本地文件夹中的JS文件,但我不能。加载html页面时,它说:
“未捕获的ReferenceError:未定义myFunction”

这是我的home.html脚本:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
    <head>
        <title>Spring Security Example</title>
        <script type="javascript" src="test.js"></script>
    </head>
    <body onload="myFunction()">
        <h1>Welcome!</h1>

        <p>Click <a href="/hello">here</a> to see a greeting.</p>
    </body>
</html>

这是我的js文件所在的位置,而htmls放置在模板文件夹中。

这是我的mvcConfig代码:

package hello;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;


@Configuration
public class MvcConfig implements WebMvcConfigurer {

    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/home").setViewName("home");
        registry.addViewController("/").setViewName("home");
        registry.addViewController("/hello").setViewName("redirect:http://localhost:3000/home.html");
        registry.addViewController("/login").setViewName("login");
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
    if (!registry.hasMappingForPattern("/webjars/**")) {
        registry.addResourceHandler("/webjars/**").addResourceLocations(
                "classpath:/META-INF/resources/webjars/");
    }
    if (!registry.hasMappingForPattern("/**")) {
        registry.addResourceHandler("/**").addResourceLocations("classpath:/META-INF/resources/", "classpath:/resources/","classpath:/static/", "classpath:/public/");
    }

    registry.addResourceHandler("/resources/**")
        .addResourceLocations("/resources/");


}

}

WebSecurityConfig代码:

package hello;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/home","/resources/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }

@Bean
@Override
public UserDetailsService userDetailsService() {
    UserDetails user =
         User.withDefaultPasswordEncoder()
            .username("user")
            .password("password")
            .roles("USER")
            .build();

    return new InMemoryUserDetailsManager(user);
}

}

无论文件夹位于src / main / resources中,您都可以这样配置它们,在安全配置类中创建此方法,通常我们将静态资源放在src / main / resources中的静态文件夹中。

//this method allows static resources to be neglected by spring security
        @Override
        public void configure(WebSecurity web) throws Exception {
            web
                .ignoring()
                .antMatchers("/resources/**", "/static/**", "/css/**", "/js/**", "/images/**","/assets/**","/fonts/**","/dis/**","/vendor1/**");
        }

WebSecurityConfig类中,将permitAll设置为仅'/''/home''/resources/**'。匿名用户无需安全检查即可访问这三个端点。

对于test.js文件,src指向当前URL中的test.js。因此,当您在本地主机上运行它时,浏览器会尝试将test.js作为http://localhost:{port}/{current-page-url}/test.js

来查找

例如,如果页面位于/home下,则浏览器将调用http://localhost:8080/home/test.js,但是根据您在WebSecurityConfig中的定义,除/home本身以外的任何调用都将被阻止春季安全。 (/home/home/**不同)

因此,您需要做的就是将src URL更改为<script src="/resources/test.js"></script>,因为/resources/**端点下的任何内容都可以被任何人访问,并且已经在{{1 }}

MvcConfig

希望这会有所帮助!快乐编码:)

添加:

此外,在 registry.addResourceHandler("/resources/**") .addResourceLocations("classpath:/"); 标记中,您应该将<script>属性更改为type,或者只需删除该属性即可使用。
