Spring Cloud Contract ContractVerifierTest.java 未生成

Question

所以我正在尝试用 Java 编写合约，但问题是验证测试根本没有运行。我试过用 Groovy 编写合约，运行良好，不知道有什么区别。

插件是否缺少一些配置？我正在关注来自here 的示例项目。

这是pom.xml

这是用Java编写的合约

package contracts;

import org.springframework.cloud.contract.spec.Contract;

import java.util.function.Consumer;
import java.util.function.Supplier;

public class UserControllerContracts implements Supplier<Contract> {
    @Override
    public Contract get() {
        return Contract.make(new Consumer<Contract>() {
            @Override
            public void accept(Contract c) {
                c.name("Get All User Contract");
                c.description("Contract for /users and /user/all");
                
                c.request(request -> {
                    request.method(request.GET());
                    request.url("/user/all");
                });
    
                c.response(response -> {
                    response.status(response.OK());
                    response.body("[{\"id\":1,\"email\":\"user@email.com\",\"password\":\"password\",\"name\":\"User\"}]");
                });
            }
        });
    }

    public static class User {
        Integer id;
        String email;
        String password;
        String name;

        public User(Integer id, String email, String password, String name) {
            this.id = id;
            this.email = email;
            this.password = password;
            this.name = name;
        }
    }
}

这是用 Groovy 编写的合约

package contracts

import org.springframework.cloud.contract.spec.Contract

Contract.make {
    description 'Should return all user in database'

    request {
        method GET()
        url '/user/all'
    }

    response {
        status OK()
        headers {
            contentType applicationJson()
        }
        body '''
            [{
                "id": 1,
                "email": "user@email.com",
                "password": "password",
                "name": "User"
            }]
        '''
    }
}

您使用了错误版本的插件。看看你通过 2020.0.x 发布火车插件使用 3.0.x 版本的合同。由于旧插件生成 junit4 测试，因此最新启动不会运行它。只需将插件升级到最新的 3.0.x 版本即可。
