SPRING

스프링 부트 프로젝트에 메소드 기반 보안을 어떻게 추가합니까?

스프링 부트 프로젝트에 메소드 기반 보안을 추가하고 싶다.

PermissionEvaluator 및 MethodSecurityExpressionHandler 빈을 추가하고 @EnableGlobalMethodSecurity (prePostEnabled = true) 및 @PreAuthorize ( "isAuthenticated () 및 hasPermission (#param, 'somePermissionName')") 메소드에 주석을 달아 주면됩니다.

그러나 PermissionEvaluator 빈을 추가 한 후에

@Bean
public PermissionEvaluator permissionEvaluator() {
    HelloPermissionEvaluator bean = new HelloPermissionEvaluator();
    return bean;
}

IllegalArgumentException가 발생합니다 : "ServletContext는 기본 서블릿 처리를 구성하는 데 필요합니다"

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.web.servlet.HandlerMapping org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport.defaultServletHandlerMapping()] threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

웹에서 찾을 수있는 것은 jUnit 테스트와 관련이 있습니다. 왜이 예외가 던져 집니까? 내가 뭘 놓치고 있니? ServletContext 빈을 추가해야합니까? 그렇다면 어떻게해야합니까?

내 요구 사항은 Gradle, Spring Boot 및 java config (XML 구성 대신)입니다. 최소한의 완전한 소스는 다음과 같습니다.

Application.java

package com.domain.simple;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@EnableAutoConfiguration
@Configuration
@ComponentScan
public class Application {

    public static void main(String[] args) throws Throwable {
        SpringApplication.run(Application.class, args);
    }

}

HelloController.java

package com.domain.simple;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {

    Logger log = LoggerFactory.getLogger(HelloController.class);

    // @PreAuthorize("isAuthenticated() and hasPermission(#param, 'somePermissionName')")
    @RequestMapping(value = "/hello/{param}")
    @ResponseBody
    public String hello(@PathVariable("param") String param) {
        log.info("hello(" + param + ") called");
        return "Hello " + param;
    }
}

HelloPermissionEvaluator.java

package com.domain.simple;

import java.io.Serializable;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.security.access.PermissionEvaluator;
import org.springframework.security.core.Authentication;

public class HelloPermissionEvaluator implements PermissionEvaluator {

    Logger log = LoggerFactory.getLogger(HelloPermissionEvaluator.class);

    @Override
    public boolean hasPermission(Authentication authentication,
            Object targetDomainObject, Object permission) {
        log.info("hasPermission(Authentication, Object, Object) called");
        return true;
    }

    @Override
    public boolean hasPermission(Authentication authentication,
            Serializable targetId, String targetType, Object permission) {
        log.error("hasPermission(Authentication, Serializable, String, Object) called");
        throw new RuntimeException("ID based permission evaluation currently not supported.");
    }
}

WebSecurityConfig.java

package com.domain.simple;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.access.PermissionEvaluator;
import org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler;
import org.springframework.security.access.expression.method.MethodSecurityExpressionHandler;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
@ComponentScan
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder authManagerBuilder)
            throws Exception {
        authManagerBuilder.inMemoryAuthentication().withUser("user")
                .password("password").roles("USER");
    }

//    @Bean
//    public MethodSecurityExpressionHandler expressionHandler() {
//        DefaultMethodSecurityExpressionHandler bean = new DefaultMethodSecurityExpressionHandler();
//        bean.setPermissionEvaluator(permissionEvaluator());
//        return bean;
//    }

    // this causes an IllegalArgumentException ("A ServletContext is required to configure default servlet handling")
    @Bean
    public PermissionEvaluator permissionEvaluator() {
        HelloPermissionEvaluator bean = new HelloPermissionEvaluator();
        return bean;
    }

}

build.gradle

buildscript {
    repositories {
        maven { url "http://repo.spring.io/libs-snapshot" }
        mavenLocal()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.2.RELEASE")
    }
}

apply plugin: 'eclipse'
apply plugin: 'java'
apply plugin: 'spring-boot'

jar {
    baseName = 'simple'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
    maven { url "http://repo.spring.io/libs-snapshot" }
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-security")
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.12'
}

해결법

  1. ==============================

    1.PermissionEvaluator를 별도의 @Configuration 클래스에 두어보십시오. ServletContext가 준비되기 전에 강제로 인스턴스화 된 것처럼 보입니다 (스프링 보안 필터는 초 일찍 만들어 져야만합니다).

    2.비슷한 문제가 생겼다. 식 처리기에서 사용자 지정 권한 평가기를 구성하려면 다음과 같이 할 수 있습니다

    비슷한 문제가 생겼다. 식 처리기에서 사용자 지정 권한 평가기를 구성하려면 다음과 같이 할 수 있습니다

    public class SecurityPermissionEvaluator implements PermissionEvaluator 
    {
    //A is a spring managed bean on which permission evaluator depends
    private A a;

    @Autowired
    public  SecurityPermissionEvaluator(A a){
        this.a = a;
    }
    @Override
    public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {

        return false;
    }
}

then

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends GlobalMethodSecurityConfiguration {

    @Autowired private A a;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler =
                new DefaultMethodSecurityExpressionHandler();
        PermissionEvaluator permissionEvaluator = new SecurityPermissionEvaluator(a);
        expressionHandler.setPermissionEvaluator(permissionEvaluator);
        return expressionHandler;
    }

}

    위와 같이 명시 적으로 권한 평가기를 사용하려면 Dave가 제안한대로 (즉, 설정 파일에 권한 평가 기 Bean을 정의하십시오).
