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;
