springcloud搭建（四）服務消費者

1.加入依賴：

<dependencies>
      <dependency>
          <groupId>com.java1234.springcloud</groupId>
          <artifactId>microservice-common</artifactId>
         <version>${project.version}</version>
      </dependency>
      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
      <!-- 修改後立即生效，熱部署 -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>springloaded</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
  </dependencies>

2.創建通訊類：

package com.java1234.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

/**
 * SpringCloud相關配置
 * @author Administrator
 *
 */
@Configuration
public class SpringCloudConfig {

	/**
	 * 調用服務模版對象
	 * @return
	 */
	@Bean
	public RestTemplate getRestTemplate(){
		return new RestTemplate();
	}
	
}

3.controller：

package com.java1234.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import com.java1234.entity.Student;

/**
 * 服務消費者-學生信息控制器
 * @author Administrator
 *
 */
@RestController
@RequestMapping("/student")
public class StudentConsumerController {

	@Resource
	private RestTemplate restTemplate;
	
	private final static String PRE_HOST="http://localhost:1001";
	
	/**
     * 添加或者修改學生信息
     * @param student
     * @return
     */
    @PostMapping(value="/save")
    public boolean save(Student student){
    	return restTemplate.postForObject(PRE_HOST+"/student/save", student, Boolean.class);
    }
     
    /**
     * 查詢學生信息
     * @return
     */
    @SuppressWarnings("unchecked")
	@GetMapping(value="/list")
    public List<Student> list(){
        return restTemplate.getForObject(PRE_HOST+"/student/list", List.class);
    }
     
    /**
     * 根據id查詢學生信息
     * @return
     */
    @GetMapping(value="/get/{id}")
    public Student get(@PathVariable("id") Integer id){
        return restTemplate.getForObject(PRE_HOST+"/student/get/"+id, Student.class);
    }
     
    /**
     * 根據id刪除學生信息
     * @return
     */
    @GetMapping(value="/delete/{id}")
    public boolean delete(@PathVariable("id") Integer id){
        return restTemplate.getForObject(PRE_HOST+"/student/delete/"+id, Boolean.class);
    }
	
}

4.增加配置文件：

application.yml


server:
  port: 80
  context-path: /
 

 

 

5.創建啓動類：

package com.java1234;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;

// 不需要注入數據庫驅動
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
public class StudentConsumerApplication_80 {

	public static void main(String[] args) {
		SpringApplication.run(StudentConsumerApplication_80.class, args);
	}
}
