搭建Spring MVC+ jdbcTemplate框架

开发环境：

JDK：1.8

Tomcat：8.0.35

MySql：5.6.28

Myeclipse：2015 Stable 2.0

Maven：3.39

工具安装过程不再赘述，下面直接从零开始搭建Spring MVC+ jdbcTemplate框架

Maven默认配置下载会有点慢，点这里参看优化配置方法。

1.进入命令行，切换到目标文件夹下，注意：此步不用创建项目的文件夹。

2. 在命令行输入：mvn archetype:generate -DgroupId=公司名或公司域名 -DartifactId=项目名称 -DarchetypeArtifactId=maven-archetype-webapp -DinteractivMode=false -DarchetypeCatalog=internal，出现下图说明创建成功，文件夹内会出现项目文件夹



3.运行Myeclipse，点击菜单栏File-》Import-》，选择“Existing Maven Projects”





点击“Finish”

4.在/src/main/下创建java文件夹

5.对项目名称点右键-》Properties-》Java Build Path，选择Libraries选项卡：

a.Add Library -》JRE System Library，添加系统的JRE版本，这里用的是Spring 4.X，需要使用1.6以上的JRE版本。

b.Add Library -》MyEclipse Server Library，选择系统中安装的Tomcat8

6.双击pom.xml， 点击pom.xml选项卡,修改如下：

<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>

7.对项目名称点右键，选择Maven4Myeclipse-》Update Project，更新完成后，可部署至Tomcat浏览默认的Index.jsp页面。

8.在/springtest/src/main/java下（这里的项目名称为springtest），分别创建包：springtest.controller，springtest.model，springtest.service，springtest.Service.Impl。

9.在springtest.model下创建Person.java：

package springtest.model;

public class Person {

private String name;

private int id;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}

}

10.在springtest.service下创建PersonService.java：

package springtest.service;

import springtest.model.Person;

public interface PersonService {
void save(Person person);
void del(Person person);
void update(Person person);
void searchAll();
}

11.在springtest.service.Impl下创建PersonServiceImp.java：

package springtest.service.Impl;

import org.springframework.jdbc.core.JdbcTemplate;
import springtest.model.Person;
import springtest.service.PersonService;

public class PersonServiceImp implements PersonService{
private JdbcTemplate jdbcTemplate;

public void del(Person person) {
// TODO Auto-generated method stub

}

public void save(Person person) {

// TODO Auto-generated method stub

jdbcTemplate.update("insert into user_info values(?,?)",new Object[]{person.getId(),person.getName()});

}

public void searchAll() {
// TODO Auto-generated method stub

}

public void update(Person person) {
// TODO Auto-generated method stub

}

public JdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}

}

12.现在配置Web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>springtest</display-name>

<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>

<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/rest-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>*.qq</url-pattern>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
</web-app>

13.在/springtest/src/main/resources下创建Servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 
<context:component-scan base-package="springtest.controller" />
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/views/" p:suffix=".jsp" />

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost:3306/数据库名"></property>
<property name="username" value="root"></property>
<property name="password" value="tiger"></property>
<property name="maxActive" value="100"></property>
<property name="maxIdle" value="30"></property>
<property name="maxWait" value="500"></property>
<property name="defaultAutoCommit" value="true"></property>
</bean>

<!-- jdbc注入 -->
<bean id="jdbcTemplate"
class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource">
<ref bean="dataSource" />
</property>
</bean>

<!-- dao注入 -->
<bean id="personService" class="springtest.service.Impl.PersonServiceImp">
<property name="jdbcTemplate" ref="jdbcTemplate"></property>
</bean>
</beans>

14.在上面代码指定的数据库中创建表user_info，字段：

15.在springtest.controller下创建NewController.java：

package springtest.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import springtest.model.Person;
import springtest.service.PersonService;

@Controller
@RequestMapping("/city")
public class NewController {
@Autowired
PersonService personService;

@RequestMapping(value="start.qq",method={RequestMethod.GET})
public String startMVC (HttpServletRequest request,ModelMap modelMap){

System.out.println("ok");
Person person = new Person();
person.setId(Integer.parseInt(request.getParameter("id").toString()));
person.setName(request.getParameter("name"));
personService.save(person);
System.out.println(person.getId());
System.out.println(person.getName());
modelMap.put("person",person);

return "user/MyJsp";
}
}

16.创建如下图所示的jsp文件：

17.home.jsp代码如下：

<html>
<head>
<title>Spring MVC Tutorial by Defonds - Hello World Spring MVC
Example</title>
<style type="text/css">
body {
background-image: url('http://img.blog.csdn.net/20150827184458936');
}
</style>
</head>
<body>${message}

<br>
<br>
</body>
</html>

好了，重启tomcat，在浏览器访问http://127.0.0.1:8080/springtest/city/start.qq?id=111&name=daleiwang，效果如下：



这个时候再去看数据库，就已经添加了这条数据啦。

这里感谢两位大神的博文指导：
