eclipse-搭建maven的war项目集合spring注解方式

工具：eclipse 4.4.2 版本号：20150219-0600

jdk：1.7

1.下图创建maven工程，然后next

下图选择工程保存位置（这里选择默认），next

下图选择webapp项目（war包，mvaen默认选择的quickstart一般为jar工程），next

下图,其中

group ID：一般设置起点报名，随便定义

artifact ID：项目名称

Version：版本号名称

package:初始化类文件名称

其他暂不填finish

项目新建完成

结构

2.接下来到需要的jar

jdk=修改成官方的1.7，finish

还有

解下来下面两个版本号不太好改，直接在eclipse中改好像改不了

所以需要到项目下面去改文件

打开项目地址

例如：c:workspaceTestMaven.settings下面

找到文件org.eclipse.wst.common.project.facet.core.xml

原文件内容

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.5"/>
  <installed facet="jst.web" version="2.3"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

修改其中的jst.web和java为对应的版本

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.7"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

保存

到这么一个正常的maven web项目搭建好了

3.接下来引入spring

在pom.xml中引入相关配置文件

开始加入spring机制

首先在web.xml加载spring

    <servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <url-pattern>/web/*</url-pattern>
    </servlet-mapping>
    <!-- 配置session存在时间 -->
    <session-config>

    </session-config>
    <welcome-file-list>

    </welcome-file-list>

</web-app>

spring配置文件(这里将配置文件设定到指定位置)

其中，三个在web.xml中配置的基础文件

其中文件

hibernate.connection.username=root
hibernate.connection.password=数据库密码

和ehcache.xml（缓存文件记录）

<!-- Sets the path to the directory where cache .data files are created.

If the path is a Java System Property it is replaced by
its value in the running VM.

The following properties are translated:
user.home - User's home directory
user.dir - User's current working directory
java.io.tmpdir - Default temp file path -->
<diskStore path="user.dir"/>

<!--Default Cache configuration. These will applied to caches programmatically created through
the CacheManager.

The following attributes are required:

maxElementsInMemory - Sets the maximum number of objects that will be created in memory
eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the
element is never expired.
overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.

The following attributes are optional:
timeToIdleSeconds - Sets the time to idle for an element before it expires.
i.e. The maximum amount of time between accesses before an element expires
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that an Element can idle for infinity.
The default value is 0.
timeToLiveSeconds - Sets the time to live for an element before it expires.
i.e. The maximum time between creation time and when an element expires.
Is only used if the element is not eternal.
Optional attribute. A value of 0 means that and Element can live for infinity.
The default value is 0.
diskPersistent - Whether the disk store persists between restarts of the Virtual Machine.

新建测试类

TestCtrl内容，其中包名在spring-mvc.xml中配置spring注入机制

package com.test.web;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;


@Controller
@RequestMapping("test")
public class TestCtrl {

    @RequestMapping("index")
    public void index(HttpServletRequest req, HttpServletResponse res){
        System.out.println("coming.....");
        try {
            res.getWriter().append("you request success.");
        } catch (IOException e) {
            e.printStackTrace();
        }
        
    }
    

}

放入tomcat

启动

网站访问

http://localhost:8080/TestMaven/web/test/index

后台打印

测试service是否有注入（service注入也需要提前将需要交个spring管理的报名通知给spring，想通知在spring-component中配置）

创建TestService

TestService

package com.test.service;

public interface TestService {

}

TestServiceImpl

package com.test.service.impl;

import org.springframework.stereotype.Service;

import com.test.service.TestService;

@Service("testService")
public class TestServiceImpl implements TestService {

}

TestCtrl注入Service

package com.test.web;

import java.io.IOException;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.test.service.TestService;


@Controller
@RequestMapping("test")
public class TestCtrl {
    @Resource
    private TestService testService;

    @RequestMapping("index")
    public void index(HttpServletRequest req, HttpServletResponse res){
        System.out.println("coming....."+testService);
        try {
            res.getWriter().append("you request success.");
        } catch (IOException e) {
            e.printStackTrace();
        }
        
    }
    

}

重新启动，访问地址http://localhost:8080/TestMaven/web/test/index

后台打印

到此，整个项目基本完成

后期在对项目进行spring权限控制等，另开文章，尽请期待
