maven + spring boot + spring data jpa + thymeleaf框架整合
Spring Boot简介
Spring Boot是基于Spring4的条件注册的一套快速开发整合包,用于快速、敏捷地开发新一代基于Spring框架的应用程序。
JPA和spring data jpa简介
JPA(Java Persistence API)是Sun官方提出的Java持久化规范。它为Java开发人员提供了一种对象/关联映射工具来管理Java应用中的关系数据。它的出现主要是为了简化现有的持久化开发工作和整合ORM技术。
Spring data jpa是在JPA规范下提供了Repository层的实现,但是使用哪一种ORM需要你来决定(默认用Hibernate实现)。
thymeleaf简介
Thymeleaf是一款用于渲染XML/XHTML/HTML5内容的模板引擎。
整合过程介绍(开发工具:IntelliJ IDEA )
项目结构如下:
1、创建maven项目,pom.xml配置如下:
<?xml version="1.0" encoding="UTF-8"?>
<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>
<groupId>com.xieke.test</groupId>
<artifactId>springboot-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.1.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.39</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-thymeleaf -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
<version>1.4.0.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>1.5.1.RELEASE</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>

<artifactId>spring-boot-maven-plugin</artifactId>

<artifactId>springloaded</artifactId>
<version>1.2.5.RELEASE</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</project>
2、添加application.properties文件到 resources下,配置如下:
server.port=8080
server.tomcat.uri-encoding=utf-8
#MySQL
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=999999
#Spring Data JPA(Spring Boot 默认使用hibernate作为JPA的实现)
spring.jpa.database=MYSQL
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
#视图层控制(view默认配置)
spring.mvc.view.prefix=classpath:/templates/
spring.mvc.view.suffix=.html
spring.mvc.static-path-pattern=/static/**
# 是否启用thymeleaf模板解析
spring.thymeleaf.enabled=true
# 是否开启模板缓存(建议:开发环境下设置为false,生产环境设置为true)
spring.thymeleaf.cache=false
3、在resources下新建static/ scripts,templates/ user文件夹用来存放js,html文件
3.1 index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<script src="../../static/scripts/jquery.min.js"></script>
<script src="../../static/scripts/test.js"></script>
<title>Title</title>
</head>
<body>
<h1>TEST PAGE</h1>
</body>
</html>
3.2 test.js
$(document).ready(function (){
alert("OK TEST");
});
4、java 主要配置文件如下:
4.1 JPA配置类JpaConfiguration.java
package com.xieke.test.configuration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Order(Ordered.HIGHEST_PRECEDENCE) // 最高值优先,默认最低值优先
@Configuration
@EnableTransactionManagement(proxyTargetClass = true)
@EnableJpaRepositories(basePackages = "com.xieke.test.repository")
@EntityScan(basePackages = "com.xieke.test.entity")
public class JpaConfiguration {
@Bean
PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor(){
return new PersistenceExceptionTranslationPostProcessor();
}
}
4.2 项目启动类Entry.java
package com.xieke.test.configuration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* 项目启动入口,配置包根路径
*/
@SpringBootApplication
@ComponentScan(basePackages = "com.xieke.test")
public class Entry {
public static void main(String[] args) throws Exception {
SpringApplication.run(Entry.class, args);
}
}
