spring3.2+mybatis3.2+maven整合
用maven管理spring+mybatis的项目：
这里主要讲述的是maven中的pom.xml文件的配置，以及在maven构建过程中会碰到的几个问题（我用的是maven4.4的版本）：
首先一步一步配置项目所需要的依赖：为了便于管理，最好是版本号和依赖分开来写：
如以下的配置方式：
<properties>
<!-- spring版本号 -->
<spring.version>3.2.4.RELEASE</spring.version>
<!-- mybatis版本号 -->
<mybatis.version>3.2.4</mybatis.version>
<!-- log4j日志文件管理包版本 -->
<slf4j.version>1.6.6</slf4j.version>
<log4j.version>1.2.9</log4j.version>
<!-- mysql 版本 -->
<mysql.version>5.1.29</mysql.version>
<!-- google json 版本 -->
<gson.version>2.5</gson.version>
<!-- junit 版本 -->
<junit.version>4.11</junit.version>
<!-- com.google.guava version 版本 -->
<guava.version>19.0</guava.version>
<!-- commons-codec 版本 -->
<commons-codec.version>1.10</commons-codec.version>
</properties>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
关于jar包依赖的配置没什么可说的，下面主要是说说项目打包过程中出现的几个问题：
1：打包后在target目录下找不到项目的spring和mybatis的xml文件；
默认情况下，maven打包时，只会编译.java的文件，而spring.xml的文件管理这所有的类的依赖，所以这个错误就是找不到相应的类；

当然项目中不仅只有spring和mybatis的xml文件，还包括sql的映射文件，在pom文件下应该加上以下配置，让maven打包的时候xml文件也能够打包：
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
这样就能在打包时包，src/main/resources和src/main/java下的xml文件都打包；
2：问题2：MalformedByteSequenceException:3 字节的 UTF-8 序列的字节 3 无效；
如果没有配置编码插件，在打包时是会包这个错误的，只需在pom.xml文件下如下配置就可以了：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
这两个问题是maven打包时遇到的问题，也困扰了我很久，终于解决了；
