使用Eclipse搭建Maven项目（最近做个人网站，顺便记下来以防后面的项目要用）

1、打开Eclipse，File-New-Maven Project



2、点击下一步，如图所示选择webapp



3、点击下一步，如图自己填写



4、这样，我们就完成了创建Maven项目，架构如图所示：



5、接下来整合SSM框架，在pom.xml中添加jar包，在此文件中添加的包会自动下载到事先配置好的maven仓库：

代码如下：

6、在src/main/resources下添加配置文件：spring-mybatis.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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描 -->
<context:component-scan base-package="com.lzs.PersonalWeb" />
<!-- 引入配置文件 -->
<!-- <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" /> </bean> -->

<context:property-placeholder
ignore-unresolvable="true" location="classpath:jdbc.properties" />
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="${jdbc.initialSize}"></property>
<!-- 连接池最大数量 -->
<property name="maxActive" value="${jdbc.maxActive}"></property>
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="${jdbc.maxIdle}"></property>
<!-- 连接池最小空闲 -->
<property name="minIdle" value="${jdbc.minIdle}"></property>
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="${jdbc.maxWait}"></property>
</bean>

<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/lzs/PersonalWeb/dao/*.xml"></property>
</bean>

<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.lzs.PersonalWeb.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>

<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

</beans>

7、配置数据库连接池jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/personalweb?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456
#配置初始化大小、最小、最大
jdbc.initialSize=1
jdbc.minIdle=2
jdbc.maxIdle=20
jdbc.maxActive=20
#配置获取连接等待超时的时间
jdbc.maxWait=60000
#配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
jdbc.timeBetweenEvictionRunsMillis=60000
#配置一个连接在池中最小生存的时间，单位是毫秒
jdbc.minEvictableIdleTimeMillis=300000
filters=stat,wall

8、配置日志：log4j.properties

log4j.rootLogger=INFO,Console,File

log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Encoding=utf-8
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss} %C{1}@(%F:%L):%m%n

log4j.appender.File = org.apache.log4j.RollingFileAppender
log4j.appender.File.File = logs/ssm.log
log4j.appender.File.MaxFileSize = 10MB
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

#开发环境记录SQL日志
log4j.logger.com.eliteams=debug
log4j.logger.com.ibatis=debug
log4j.logger.java.sql.Statement=debug
log4j.logger.java.sql.PreparedStatement=debug,stdout

9、开始整合spring-mvc，配置spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.lzs.PersonalWeb.controller" />
<!--避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ，视图模式配置 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>

<!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 默认编码 -->
<property name="defaultEncoding" value="utf-8" />
<!-- 文件大小最大值 -->
<property name="maxUploadSize" value="10485760000" />
<!-- 内存中的最大值 -->
<property name="maxInMemorySize" value="40960" />
</bean>
</beans>

10、修改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" version="3.0">
<display-name>Archetype Created Web Application</display-name>
<!-- Spring和mybatis的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring-mybatis.xml
</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<!-- Spring MVC servlet -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<!-- 本人习惯使用加rest/前缀 -->
<!-- <url-pattern>*.do</url-pattern> -->
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<!-- 欢迎页面，访问/rest/index方法，也可以直接指定一个jsp(index.jsp) -->
<welcome-file>rest/index</welcome-file>
</welcome-file-list>
</web-app>

11、至此，maven整合ssm基本搭建完成，结构树如下：



此时，会发现项目中带红叉，查看problems中，显示如下错误：



经百度获得解决方法：
1、先改web.xml中webapp节点:
 
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
 
然后关闭Eclipse,改项目下的.settings\org.eclipse.wst.common.project.facet.core.xml.将版本改成为3.1：<installed
facet="jst.web" version="3.1"/>,再启动Eclipse.
 
右键项目->Maven->Update Project
2、在pom.xml配置文件的<build></build>中加入如下语句：
<plugins>  
<plugin>  
<groupId>org.apache.maven.plugins</groupId>  
<artifactId>maven-compiler-plugin</artifactId>  
<configuration>  
<source>1.7（修改成自己JDK的版本）</source>  
<target>1.7（修改成自己JDK的版本）</target>  
</configuration>  
</plugin>  
</plugins>  
右键项目->Maven->Update Project

12、下面添加测试代码：在src/main/java下添加model层、service层、dao层、controller层：



自动生成dao层和model层：http://blog.csdn.net/qq_31874947/article/details/78392367
User.java:

package com.lzs.PersonalWeb.model;

}

public String getSex() {

}

public Double getHeight() {

}

public void setHeight(Double height) {
this.height = height;
}

public Date getBirth() {

}

public void setBirth(Date birth) {

}

public String getConstellation() {
return constellation;
}

public void setConstellation(String constellation) {
this.constellation = constellation == null ? null : constellation.trim();
}

public String getHobby() {
return hobby;
}

public void setHobby(String hobby) {
this.hobby = hobby == null ? null : hobby.trim();
}

public String getQq() {
return qq;
}

public void setQq(String qq) {
this.qq = qq == null ? null : qq.trim();
}

public String getEducation() {
return education;
}

public void setEducation(String education) {
this.education = education == null ? null : education.trim();
}

public String getBg() {
return bg;
}

public void setBg(String bg) {
this.bg = bg == null ? null : bg.trim();
}

public String getPhone() {
return phone;
}

public void setPhone(String phone) {
this.phone = phone == null ? null : phone.trim();
}

public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email == null ? null : email.trim();
}
}
