部署带有服务的Cloudfoundry应用程序（春季启动） [英] Deploy Cloudfoundry app with Service (Spring Boot)

问题描述

在cloudfoundry中部署带有服务的应用程序时遇到问题。已经有一个星期了，我找不到解决方案。您能告诉我我的代码有什么问题吗？顺便说一句，我可以在没有服务的情况下进行部署，但是在绑定服务并尝试连接到数据库时会挂起部署。我在部署中使用spring sts。我希望有人能帮助我解决这个问题。

I'm having a problem deploying an app with a service in cloudfoundry. It's been a week and i can't find a solution. Can you tell me guys whats wrong with my code? BTW, i can deploy without a service but when binding a service and trying to connect to the database hangs the deployment. I'm using spring sts in my deployment. I hope someone can help me figure this out.

这是我的参考btw：

this is my reference btw : https://github.com/jwlayug/spring-cloud and https://github.com/jwlayug/spring-cloud/tree/master/spring-service-connector

我的代码

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends AbstractCloudConfig {
    @Bean
    public DataSource inventoryDataSource() {
        return connectionFactory().dataSource("jwlpostgre");
    }

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

@Entity
class User {
    @Id
    @GeneratedValue
    private long id;

    private String name;

    public User() {
    }

    public User(String name) {
        this.name = name;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String toString() {
        return this.name;
    }

}

interface UserRepository extends JpaRepository<User, Long> {

}

@Controller
class MyController {
    @Autowired
    UserRepository userRepository;

    @RequestMapping(value = "/")
    public String sample(Model model) {
        model.addAttribute("sample", "Sample");
        userRepository.save(new User("a"));
        userRepository.save(new User("b"));
        userRepository.save(new User("c"));
        model.addAttribute("findall", userRepository.findAll());
        for (User user : userRepository.findAll()) {
            System.out.println(user.getName());
        }
        return "sample";
    }
}

推荐答案

如果您没有多个数据库数据源，则无需添加该bean或将其命名。

if you don't have more than one database datasource, you don't need to add that bean or name it.

请确保您排除数据源自动配置，因为这会引起问题。

make sure you exclude datasource auto config as this causes an issue.

package com.mycompany.myapp;

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

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = DataSourceAutoConfiguration.class) 
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

使用当前版本对我有用。

using the current versions worked for me. Update to the latests and greatest.
