服务提供者使用Eureka Client组件创建首先在父项目中创建Eureka Client Server项目（Maven）创建完成以后，修改pom.xml文件
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>com.wenqi.springcloud</artifactId> <groupId>org.example</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>EurekaClient</artifactId> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> <version>2.0.2.RELEASE</version> </dependency> </dependencies></project>
编写application.yml文件
server: port: 8010 # 当前服务注册在eureka server上的名称spring: application: name: provider # 当前注册中心的访问地址eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ # 是否将当前服务的ip注册到Eureka Server instance: prefer-ip-address: true
创建启动类
@SpringBootApplicationpublic class ProviderApplication { public static void main(String[] args) { SpringApplication.run(ProviderApplication.class,args); }}
启动启动类，这时候访问http://localhost:8761/ 可以看到服务注册进来了。接下来进行增删改查的简单业务服务操作
创建实体类
@Data@AllArgsConstructor@NoArgsConstructorpublic class Student { private long id; private String name; private int age;}
创建repository
public interface StudentRepository { public Collection<Student> findAll(); public Student findById(long id); public void saveOrUpdate(Student student); public void deleteById(long id);}
创建repository实现类
@Repositorypublic class StudentRepositoryimpl implements StudentRepository { private static Map<Long,Student> studentMap; static { studentMap = new HashMap<Long, Student>(); studentMap.put(1L,new Student(1L,"张三",22)); studentMap.put(2L,new Student(2L,"王五",20)); studentMap.put(3L,new Student(3L,"李四",21)); } public Collection<Student> findAll() { return studentMap.values(); } public Student findById(long id) { return studentMap.get(id); } public void saveOrUpdate(Student student) { studentMap.put(student.getId(),student); } public void deleteById(long id) { studentMap.remove(id); }}
实现增删改查操作 controller
@RestController@RequestMapping("/student")public class StudentController { @Autowired private StudentRepository studentRepository; @GetMapping("/findAll") public Collection<Student> findAll(){ return studentRepository.findAll(); } @GetMapping("/findById/{id}") public Student findById(@PathVariable("id") long id){ return studentRepository.findById(id); } @PostMapping("/save") public void save(@RequestBody Student student){ studentRepository.saveOrUpdate(student); } @PutMapping("/update") public void update(@RequestBody Student student){ studentRepository.saveOrUpdate(student); } @DeleteMapping("/delete/{id}") public void deleteById(@PathVariable("id") long id){ studentRepository.deleteById(id); }}
启动Eureka Client，并启动Eureka Server。使用postman工具进行测试
postman的使用自己下去进行了练习，不得不说测试还是很有必要的。
