spring boot+jpa框架搭建
1.首先依赖jar的引入
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<jackson.version>2.6.1</jackson.version>
</properties>

<!--spring4.0以上json和java对象的转换jackson包 spring4.0以上需要jackson2.6版本 -->

</dependency>
<dependency>

<dependency>

</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.dk.zb.ZbApplication</mainClass>
<!--fork : 如果没有该项配置devtools不会起作用，即应用不会restart -->
<fork>true</fork>
<addResources>true</addResources><!--支持静态文件热部署-->
</configuration>
</plugin>
</plugins>
</build>其中
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
<scope>true</scope>
</dependency>spring-boot-devtools是spring boot热部署要引入的依赖jar，引入jar包后，在build里还要加上以下，才能生效
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.dk.zb.ZbApplication</mainClass>
<!--fork : 如果没有该项配置devtools不会起作用，即应用不会restart -->
<fork>true</fork>
<addResources>true</addResources><!--支持静态文件热部署-->
</configuration>
</plugin>
</plugins>2.jar包引入到maven成功后，配置application.properties文件
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://212.196.203.171:3306/mysql
spring.datasource.username=root
spring.datasource.password=123456
spring.jpa.hibernate.ddl-auto=update
#显示sql语句
spring.jpa.show-sql=true
spring.jackson.serialization.indent_output=true
#服务器访问端口设置
server.port=9000
#服务器访问根路径设置
server.context-path=/ZIBShopping
#设置静态资源路径，多个以逗号分隔
#spring.resources.static-locations=classpath:sAtatic/,file:static/
#禁用devtools模块的功能
spring.devtools.restart.enabled=true
#添加那个目录的文件需要restart
spring.devtools.restart.additional-paths=src/main/java
#排除那个目录的文件不需要restart
spring.devtools.restart.exclude=META-INF/maven/**,META-INF/resources/**,resources/**,*.properties设置实体表的创建更新
spring.jpa.hibernate.ddl-auto=updateupdate：表示表如果存在，则更新
create：表示表如果存在，则drop，然后create
3.spring boot热部署设置
- 在maven中添加相关依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
<scope>true</scope>
</dependency>
- 在maven添加插件
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!--fork : 如果没有该项配置devtools不会起作用，即应用不会restart -->
<fork>true</fork>
<addResources>true</addResources><!--支持静态文件热部署-->
</configuration>
</plugin>
- idea中配置
1. File-》settings-》Compiler 然后勾选 Build Project automatically
2. 按ctrl+shift+alt+/ 然后选中Registery... 勾选 compiler.automake.allow.when.app.running
