Question

我正在尝试监视我的服务类，但是我遇到了异常，请您帮我在这里做错了什么

我尝试使用下面的代码创建Spy对象，但未按预期工作

def myService = Spy(MyService)

MyInterface.groovy

interface MyInterface<T> {

    public String welcome(T t);

}

MyService.groovy

@Service
class MyService implements MyInterface<WelcomeMessage> { 

@Override
    String welcome(WelcomeMessage welcomeMessage) {

    try { 
        // Business logic

    } catch (ex) { 

        // Catch Exception
    }

    }

}

import spock.lang.Specification
class myServiceTest extends Specification {
    def "testWelcome"() {
        setup: "create mock object"
        def myService = Spy(MyService)

        and: " and object with mock data"
        when: "invoke welcomeMessage"
        then: "Expecting no exception is thrown"
    }
}

例外：

您能否提供spring，spock和cglib的版本？

对于这些，我无法重现所描述的问题：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>5.1.4.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.1.4.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.spockframework</groupId>
        <artifactId>spock-core</artifactId>
        <version>1.2-groovy-2.5</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib</artifactId>
        <version>3.2.10</version>
        <scope>test</scope>
    </dependency>

我拥有的代码几乎相同（相反，我使用WelcomeMessage的{{1}}）：

MyInterface.groovy

String

MyService.groovy

interface MyInterface<T> {
    String welcome(T t);
}

MyServiceTest.groovy

import org.springframework.stereotype.Service

@Service
class MyService implements MyInterface<String> {
    @Override
    String welcome(String welcomeMessage) {
        return welcomeMessage
    }
}

尝试使用Spock间谍时CGLIB抛出IllegalArgumentException
