spring3.2+mybatis3.2+maven整合

Posted 2020-08-09

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；
