接上一篇:
eclipse 创建maven 项目 动态web工程完整示例
eclipse maven工程自动添加依赖设置
maven工程可以在线搜索依赖的jar包,还是非常方便的
但是有的时候可能还需要设置下
eclipse不能在线搜索jar包 报错
如果搜索不到内容,或者有报错信息(index downloads are disabled ,search results may be incomplete)
windows preference maven 勾选上
然后 windows show views
rebuild一下
就可以搜索了
注意这个地方的scope,暂且不管
我们输入spring-webmvc,找到我们需要的,单击一下就好了
还有就是,version只要是存在的版本,我们可以手动写的
添加了之后,顺手更新了下项目(注意,不是必须要做的哈,只是我手欠了)不过你早晚或许都会需要更新下
然后捏
尼玛,报错了....
想了一下不应该啊,都修改好了的
回头一看
我的jdk版本,还有eclipse的一些配置,都尼玛改回来了,还原了....
肿么了这是?
忘记设置了!!!!!
maven update project后版本还原,jdk还原了!
Maven 3.0 source和target的默认设置都是1.5，与运行Maven时的JDK版本无关，除非在项目的POM文件中显示的指定一个版本，否则每次更新后都会使用编译器默认的source/target版本1.5。
所以,把原来修改过的东西修改回去先......
然后pom.xml中显示的指定这一段
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<!-- 指定source和target的版本 -->
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
(如果有build标签了,就是plugins这一段)
然后在更新下 update project
刚才的错误就没了
我们刚才引入了spring-context spring-webmvc发现多了好几个
这就是maven好处,它所依赖的包,会自动下载的...
我们再继续添加一个mybatis-spring
最后的结果就是这样子
HelloWorld.java
package springmvcMaven;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class HelloWorld {
public static void main(String[]args){
ApplicationContext ctx = new FileSystemXmlApplicationContext("src/helloWorld.xml");
HelloWorldSpringBean helloWorldSpringBean = (HelloWorldSpringBean)ctx.getBean("myHelloWorld");
helloWorldSpringBean.show();
}
}
HelloWorldSpringBean.java
package springmvcMaven;
public class HelloWorldSpringBean {
private String hello;
public String getHello(){
return hello;
}
public void setHello(String hello){
this.hello=hello;
}
public void show(){
System.out.println("--message--"+getHello());
}
}
helloWorld.xml 在src的根目录下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="myHelloWorld" class="springmvcMaven.HelloWorldSpringBean">
<property name="hello">
<value>hello World spring!</value>
</property>
</bean>
</beans>
项目的结构就是这样子
右键 run as,打印信息成功
spring跑通
现在开始测试一下springmvc的情况
为了接下来的项目的规范性,我们重新规划下项目的结构以及配置文件
这个是最新的结构
说白了新建了几个包,用于区分不同的功能划分,controller用于控制跳转,domain用于存放JavaBean,dao用于操作数据库相关,service用于相关接口的实现
mapper用于mybatis的xml文件
另外还有两个配置文件
ApplicationContext.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"

<context:component-scan base-package="com.noteless.bbs.domain" />
</beans>
springmvc.xml设置了自动扫描的controller的类包,并且设置了视图解析

<beans xmlns="http://www.springframework.org/schema/beans"

</bean>
</beans>
web.xml 中指定了配置文件的路径,以及配置了servlet

controller里面新建一个LoginController.java
package com.noteless.bbs.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class LoginController {
@RequestMapping(value="/welcome")
public String toLoginPage(HttpServletRequest request){
return "welcome";
}
}
在views下面新建了一个欢迎页面
welcome.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>标题</title>
</head>
<body>
欢迎光临!
<br>
欢迎光临!
</body>
</html>
我们启动server,然后运行项目
可以看到springmvc的配置也没有问题
接下来是链接数据库,以及配置mybatis
刚才引用了一些包但是还远远不够,此处不再一一介绍没一个引用的包的作用以及何时引入了,贴出来我用到的包,
有了这些包就可以开始我们后续的项目了
注意;如果是项目搭建初期,如果有报错,我建议,先看看常用的或者必须要用到的一些包是不是缺失,都弄过来
如果还有报错,再去看具体的原因
当然如果你非常熟悉的话,看一眼报错就知道缺什么包那就最好了,估计你要是还在看我的文章,说明你不牛...
配置数据库以及配置mybatis
这个工程示例,是接着我的之前的文章中的示例写的,功能一样,结构不一样(之前的没用maven)
一些javaBean类以及service 都直接拿过来用了
有兴趣的翻一下其他的文章
现在的结构为:

其实,这几个文件是最重要的哈,还有jar包..
把接口 javaBean挪过来之后,配置处理好之后,测试一下,可以执行通过
这样一个完整的springmvc+mybatis+maven的项目就搭建完成了
哦,对了,还有一个log4j,它的使用也很简单
应用jar包
并且配置下配置文件即可
具体的可以参考我的工程直接eclipse导入即可了
springmvcmybatisMaven-002.rar http://pan.baidu.com/s/1sknL8rb
防止链接失效,代码都贴出来吧..
一下就是所有的代码,建议下载我的工程,导入eclipse慢慢研究
