Maven+IDEA配置SSM项目

好久都没写项目了，然后配置的时候不停出错，应该就是包冲突的问题，所以写一个demo实现简单的功能，来整理一下项目配置，以后写项目的时候就拿这个进行打底了。

创建项目

选maven-archrtype-webapp

在配置Properties时加上archetypeCatalog=internal，这个会让项目创建的时间缩短。

项目结构就是这样的，这个简单的项目就是能实现用户的登录功能，并对其进行验证。

Maven+IDEA配置SSM项目
首先配置的是pom.xml文件

<dependency>
      <groupId>junit</groupId>

    </dependency>

    <!--添加spring的依赖-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>4.1.7.RELEASE</version>

    <dependency>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
      <version>1.2</version>
    </dependency>

然后再是配置web.xml文件，这里要将默认生成的xml文件头改一改，改成3.1版本的

<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"
         metadata-complete="true">

    <servlet>
        <servlet-name>user</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationConetxt.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>user</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

</web-app>

配置application.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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">


    <!--配置整合mybatis-->
    <context:property-placeholder location="classpath:jdbc.properties"/>


    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <property name="typeAliasesPackage" value="per.hss.entity"/>
        <property name="mapperLocations" value="classpath:mappers/*.xml"/>
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="per.hss.dao"/>
    </bean>

    <context:component-scan base-package="per.hss.service"/>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

   <tx:annotation-driven transaction-manager="transactionManager"/>

    <!--配置mvc-->
    <mvc:annotation-driven/>

    <mvc:default-servlet-handler/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="suffix" value=".jsp"/>
        <property name="prefix" value="/"/>
    </bean>

    <context:component-scan base-package="per.hss.controller"/>
</beans>

配置mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <typeAliases>
        <package name="per.hss.entity"/>
    </typeAliases>
</configuration>

logback.xml

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoders are assigned the type
             ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="debug">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

jdbc.properties配置文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db_ssm?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=

至此，项目配置完成，就可以开始写代码了。

遇到的问题

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd

如果没有加入的话，会出现通配符的匹配很全面, 但无法找到元素 context:property-placeholder的声明，这个错误，所以要将applicationContext.xml中文件的头部配置完善。

如果出现NoSuchMethodError错误时，要进行查看，可能因为版本问题导致使用的有些类已经被弃用
