java - 如何将 Spock 添加到我的 Springboot 项目中？
问题描述
我正在尝试将 Spock 框架添加到我的 Spring Boot 项目中，但我可以让它工作。我添加了这些依赖项：
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-core</artifactId>
<version>1.2-groovy-2.5</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-spring -->
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-spring</artifactId>
<version>1.2-groovy-2.5</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.codehaus.gmavenplus/gmavenplus-plugin -->
<dependency>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<version>1.6</version>
</dependency>
然后我创建了这个测试：
@SpringBootTest(classes = EdoobyApiApplication.class)
class AddressServiceSpockTest extends Specification {
def "when context is loaded then all expected beans are created"() {
expect:
1 + 1 == 3
}
}
这就是我在 EdoobyApiApplication.java 上的内容
@SpringBootApplication
@EntityScan(basePackageClasses = {
EdoobyApiApplication.class,
Jsr310JpaConverters.class
})
public class EdoobyApiApplication {
@PostConstruct
void init() {
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}
public static void main(String[] args) {
SpringApplication.run(EdoobyApiApplication.class, args);
}
@Bean
public ObjectMapper getObjectMapper(){
return new ObjectMapper();
}
}
当我尝试运行测试时，出现此错误：

我不熟悉 Spock，所以我不确定是否应该添加任何其他依赖项或任何其他配置。此外，我不确定是否应该在 @SpringBootTest 中添加 EdoobyApiApplication。如果有人能给我一个寻找的方向，那就太好了。
谢谢！
解决方案
这不是 Spock 或 Spring 问题。
如果运行时方法签名与编译类时方法的签名不匹配，Java 将抛出NoSuchMethodError 。另一个编译与运行时不匹配是NoClassDefFoundError。
在这种情况下，提供Springfox springfox.documentation.spring.web.scanners.CachingOperationReadercom.google.common.base.Preconditions.checkState类编译的方法的Guava 版本似乎与运行时（或可能测试）类路径中方法的方法签名不匹配。
您应该运行mvn dependency:tree -Dverbose -Dincludes=com.google.guava:guava，如此处所述。一旦您发现哪个依赖项引入了与 Springfox 需要的版本冲突的 Guava 版本，您可以将排除项添加到其他依赖项，或者在项目中添加一个具有 Springfox 需要的版本的显式依赖项，确保运行时/测试类路径包含兼容版本。
