news2025/10/31 14:43:09

新建一个服务器提供者module子模块，类似前面建的common公共模块，名称是 microservice-student-provider-1001

pom.xml改成：

<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">

加common项目依赖，以及 springboot的 web jpa 驱动包 tomcat 连接池配置包括自动热部署配置。

application.yml配置：

server:
port: 1001
context-path: /

# 数据源配置
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/db_springcloud
username: root
password: 123456
jpa:
hibernate:
ddl-auto: update
show-sql: true
thymeleaf:
cache: false

StudentRepository接口：

package com.java1234.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;

import com.java1234.entity.Student;

/**
* 学生Repository接口
* @author Administrator
*
*/
public interface StudentRepository extends JpaRepository<Student, Integer>,JpaSpecificationExecutor<Student>{

}

StudentService接口：

package com.java1234.service;

import java.util.List;

import com.java1234.entity.Student;

/**
* 学生信息Service接口
* @author Administrator
*
*/
public interface StudentService {

/**
* 添加或者修改学生信息
* @param student
*/
public void save(Student student);

/**
* 根据id查找学生信息
* @param id
* @return
*/
public Student findById(Integer id);

/**
* 查询学生信息
* @return
*/
public List<Student> list();

/**
* 根据id删除学生信息
* @param id
*/
public void delete(Integer id);

}

StudentServiceImpl实现类：

package com.java1234.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.java1234.entity.Student;
import com.java1234.repository.StudentRepository;
import com.java1234.service.StudentService;

/**
* 学生信息Service实现类
* @author Administrator
*
*/
@Service("studentService")
public class StudentServiceImpl implements StudentService{

@Resource
private StudentRepository studentRepository;

@Override
public void save(Student student) {
studentRepository.save(student);
}

@Override
public Student findById(Integer id) {
return studentRepository.findOne(id);
}

@Override
public List<Student> list() {
return studentRepository.findAll();
}

@Override
public void delete(Integer id) {
studentRepository.delete(id);
}

}

StudentProviderController类：

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 com.java1234.entity.Student;
import com.java1234.service.StudentService;

/**
* 服务提供者-学生信息控制器
* @author Administrator
*
*/
@RestController
@RequestMapping("/student")
public class StudentProviderController {

@Resource
private StudentService studentService;

/**
* 添加或者修改学生信息
* @param student
* @return
*/
@PostMapping(value="/save")
public boolean save(Student student){
try{
studentService.save(student);
return true;
}catch(Exception e){
return false;
}
}

/**
* 查询学生信息
* @return
*/
@GetMapping(value="/list")
public List<Student> list(){
return studentService.list();
}

/**
* 根据id查询学生信息
* @return
*/
@GetMapping(value="/get/{id}")
public Student get(@PathVariable("id") Integer id){
return studentService.findById(id);
}

/**
* 根据id删除学生信息
* @return
*/
@GetMapping(value="/delete/{id}")
public boolean delete(@PathVariable("id") Integer id){
try{
studentService.delete(id);
return true;
}catch(Exception e){
return false;
}
}
}

启动类StudentProviderApplication_1001：

package com.java1234;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class StudentProviderApplication_1001 {

public static void main(String[] args) {
SpringApplication.run(StudentProviderApplication_1001.class, args);
}
}

我们运行启动类，自动生成t_student表；

我们加点数据，方便测试：
