（IDEA+Spring boot）
1.创建springboot 项目.(选择web项即可)。
2.配置application.properties
server.port=8080
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/(数据库名称)?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName = com.mysql.jdbc.Driver
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
3.配置pom.xml
添加以下依赖
数据依赖
4.创建student类
@Entity
public class Student {
@Id
@GeneratedValue
private Longid;
private Stringname;
private Longage;
private Integersex;
public LonggetId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public StringgetName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public LonggetAge() {
return age;
}
public void setAge(Long age) {
this.age = age;
}
public void setSex(Integer sex) {
this.sex = sex;
}
public IntegergetSex() {
return sex;
}
}
5.创建StudentRepository
@Repository
public interface StudentRepositoryextends CrudRepository {
StudentfindStudentById(Long id);
}
6.然后就可以去创建controller 增删改查啦！
