如何修复错误：java.lang.IllegalStateException：无法加载ApplicationContext？

Question

  

我想在Sprint Boot Controller上运行集成测试和单元测试

package com.steinko.reactspringboottutorial.webserver;

import org.springframework.stereotype.Controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;



@Controller
public class HomeController {
    @Value("${frontendurl}")
    private String frontendurl;

     private final Logger log = LoggerFactory.getLogger(HomeController.class);

    @RequestMapping("/" )
    String index(HttpServletRequest request) {
        log.info("Request Mapping");
        log.info(request.toString());
        return "index";
    }


    @RequestMapping("/frontendurl" )
    String frontendurl() {
        return frontendurl;
    }

}

  

启动Spring Boot程序的类如下：   包com.steinko.reactspringboottutorial.webserver;

import java.util.Arrays;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;

import org.springframework.boot.CommandLineRunner;



@SpringBootApplication

public class FrontendWebServer {
    public static  ConfigurableApplicationContext configurableApplicationContext;

    public static void main(String[] args) {
         configurableApplicationContext = SpringApplication.run(FrontendWebServer.class, args);
    }

     @Bean
        public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
            return args -> {

                System.out.println("Let's inspect the beans provided by Spring Boot:");

                String[] beanNames = ctx.getBeanDefinitionNames();
                Arrays.sort(beanNames);
                for (String beanName : beanNames) {
                    System.out.println(beanName);
                }

            };
        }

}

  

我想用看起来像这样的集成测试来测试控制器

package com.steinko.reactspringboottutorial.webserver;

import org.springframework.boot.test.context.SpringBootTest;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import com.steinko.reactspringboottutorial.webserver.HomeController;
import org.springframework.test.context.TestPropertySource;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;

import org.springframework.beans.factory.annotation.Autowired;
import org.junit.jupiter.api.Test;
import org.springframework.test.web.servlet.MockMvc;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.hamcrest.Matchers.containsString;

import static org.hamcrest.Matchers.containsString;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;





@ExtendWith(SpringExtension.class)
@TestPropertySource("frontendurl=localhost:4000")
@WebMvcTest(controllers = HomeController.class)


public class HomeControllerIntegrationTest {
    @Autowired
    private MockMvc mvc;

    @Test
    public void givenHomeUrl_whenGetHomePage_thenStatus200()
      throws Exception {


        mvc.perform(get("/"))
          .andExpect(status().isOk())
          .andExpect(content().contentType("text/html; charset=UTF-8"))
          .andExpect(content().string(containsString("Todo fronten")));
    }

    @Test
    public void shouldReciveFrontendUrl() throws Exception {
     this.mvc.perform(get("/frontendurl"))
     .andExpect(status().isOk())
     .andExpect(content().contentType("text/plain; charset=UTF-8"))
     .andExpect(content().string(containsString("localhost:4000")));
    }

}

  

我通过运行gradle build执行测试。 gradle.build文件如下所示：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.4.RELEASE")
    }
}
plugins { 
    id 'java'
    id 'org.springframework.boot' version '2.1.5.RELEASE'
    id "com.moowork.node" version "1.3.1"
    id 'jacoco'
}


apply plugin: 'io.spring.dependency-management'

jacoco {
    toolVersion = "0.8.3"
    reportsDir = file("$buildDir/customJacocoReportDir")
}

jacocoTestReport { 
    reports {
        xml.enabled = true
    }   
}

group = 'com.steinko.reactspringboottutorial.webserver'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    developmentOnly
    runtimeClasspath {
        extendsFrom developmentOnly
    }
}

repositories {
    mavenCentral()
}

test {
    useJUnitPlatform()
}

sourceSets {
  main {
    resources {
       srcDirs = [ 
                   'src/main/resources'

                ]
    }
  }
}

ext {
    set('springCloudVersion', "Greenwich.SR1")
}



dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.cloud:spring-cloud-gcp-starter'
    implementation 'org.springframework.cloud:spring-cloud-starter-sleuth'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.3.1'
    testImplementation 'org.junit.jupiter:junit-jupiter-params:5.2.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.3.1'
}



dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}


node {
    /* gradle-node-plugin configuration
       https://github.com/srs/gradle-node-plugin/blob/master/docs/node.md
       Task name pattern:
       ./gradlew npm_<command> Executes an NPM command.
    */
    // Version of node to use.
    version = '10.16.0'
    // Version of npm to use.
    npmVersion = '6.9.0'
    // If true, it will download node using above parameters.
    // If false, it will try to use globally installed node.
    download = false
}

  

执行测试结果时出现错误信息   java.lang.IllegalStateException：无法加载ApplicationContext

     

我该怎么做才能加载ApplicationContext？
