1.先看看整体项目的一个架构，parent 项目父依赖包，用于管理我们的依赖，provider 服务提供方,consumer 消费者。
2.创建parent 项目
1)创建无骨架的maven pom项目
2)修改pom包 如下步骤：
https://projects.spring.io/spring-cloud/ 修改maven parent
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<dependencyManagement>
<dependencies>
<!-- 添加spring-cloud 依赖 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.SR1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
</dependencyManagement>
<!-- 定义JDK编译环境 -->
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
<!-- 添加子模板 -->
<modules>
<module>../provider</module>
</modules>
3.添加provider 服务提供项目
右键选择》new 》spring-start-project
修改provider服务提供方pom文件如下：
修改application.properties文件为yml 文件（红色部分为大小写转换）
编写代码部分：
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public UserInfo getUserInfo(Integer userId) {
return userMapper.getUserById(userId);
}
}
@Mapper
public interface UserMapper {
@Select("SELECT user_id,user_name,user_birth FROM tb_user WHERE user_id = #{userId}")
public UserInfo getUserById(@Param(value = "userId") Integer userId);
}
public class UserInfo implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Integer userId;
private String userName;
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date userBirth;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Date getUserBirth() {
return userBirth;
}
public void setUserBirth(Date userBirth) {
this.userBirth = userBirth;
}
}服务提供方到此完成 可以启动访问：http://localhost:8080/book/books
4.添加消费consumer项目，直接复制provide修改相关文件如下
provider-consumer pom文件修改
添加代码部分：
@SpringBootApplication
@RestController
public class ProviderApplication {
@Value("${spring.application.name}")
private String applicationName;
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ProviderApplication.class, args);
}
}
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private RestTemplate restTemplate;
@RequestMapping("/warp/get/{userId}")
public UserInfo getUser(@PathVariable Integer userId) {
return restTemplate.getForObject("http://localhost:8099/user/get/"+userId, UserInfo.class);
}
}
public class UserInfo implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Integer userId;
private String userName;
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date userBirth;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Date getUserBirth() {
return userBirth;
}
public void setUserBirth(Date userBirth) {
this.userBirth = userBirth;
}
}
//application.yml文件
server:
port: 8100
spring:
application:
