我们新建module公共模块项目 microservice-common,主要是放一些其他项目公用的东西,比如实体类,工具类等等;
详细步骤 请看 一头扎进springcloud 课程
新建module,
勾选 create a simple project 取下module 名称 mircoservice-common
这里用默认的jar
pom.xml 加下 jpa和 mysql驱动包依赖
<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.java1234.springcloud</groupId> <artifactId>microservice</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>mircoservice-common</artifactId> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> </dependencies> </project>
我们新建Student实体
package com.java1234.entity; import java.io.Serializable; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Table; /** * 学生信息实体 * @author Administrator * */ @Entity @Table(name="t_student") public class Student implements Serializable{ /** * */ private static final long serialVersionUID = 1L; @Id @GeneratedValue private Integer id; // 编号 @Column(length=50) private String name; // 姓名 @Column(length=50) private String grade; // 年级 public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getGrade() { return grade; } public void setGrade(String grade) { this.grade = grade; } }
包括映射
当然我们数据库里也提前建一个db_springcloud数据库;
