使用Service（Spring Boot）部署Cloudfoundry应用程序

标签： spring-mvc cloudfoundry spring-boot

我在使用cloudfoundry中的服务部署应用时遇到问题。这是一个星期，我找不到解决方案。你能告诉我那些人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。我希望有人可以帮我解决这个问题。

这是我的参考btw： https://github.com/jwlayug/spring-cloud和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";
    }
}

Spring Cloud的AbstractCloudConfig实现了BeanFactoryAware，并且它执行了一些bean查找/添加。我认为让您的Application类从AbstractCloudConfig扩展会导致应用程序上下文创建和刷新的顺序出现问题。尝试将dataSource @Bean方法移出Application并进入单独的@Configuration类。

如果您没有多个数据库数据源，则不需要添加该bean或为其命名。

确保排除数据源自动配置，因为这会导致问题。

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);
    }
}

使用当前版本为我工作。更新到最后和最伟大的。

我最好的猜测是你在Spring Cloud上有一个旧版本，它没有绑定，因为环境变量格式发生了变化。或者可能是您实际上没有具有该标识符的数据库。 （顺便说一下，Spring Cloud项目是here - 您引用的链接来自fork。）
