spring 和hibernate项目制作可执行的jar包
如何把spring和hibernate项目制作可运行的jar包呢?
就是在命令行中运行 java -jar xxx.jar 就可以运行java程序.例如
我的这个项目使用了hibernate和spring,不是web项目.
构建工具:maven
IDE:eclipse
目录结构如下:
上图中beans.xml是spring的配置文件,内容如下:
<?xml version="1.0" encoding="UTF-8"?>

jdbc.properties内容:
jdbc.driverClassName=oracle.jdbc.driver.OracleDriver jdbc.url=jdbc:oracle:thin:@localhost:1521:whuang jdbc.username=whuang jdbc.password=whuang
如何打成可执行的jar包呢?
(1)修改读取spring配置文件的方式
在eclipse中使用
new ClassPathXmlApplicationContext("beans.xml", "dao.xml");
打成jar包的话,要改成:
new FileSystemXmlApplicationContext("beans.xml", "dao.xml");
(2)修改beans.xml中读取jdbc.properties的方式
原来是:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <value>classpath:jdbc.properties</value> </property> </bean>
打成jar,就需要改为:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <value>jdbc.properties</value> </property> </bean>
(3)maven中生成可执行jar的方式需要改maven plugin
原来使用
<plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <appendAssemblyId>false</appendAssemblyId> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive> <manifest> <mainClass>com.jn.NotepadApp</mainClass> </manifest> </archive> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>assembly</goal> </goals> </execution> </executions> </plugin>
打成jar,就需要改为:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>1.4</version> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> <mainClass>com.jn.NotepadApp</mainClass> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.handlers</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.schemas</resource> </transformer> </transformers> </configuration> </execution> </executions> </plugin>
打开cmd,进入项目所在目录
运行 mvn clean package -U
就可以生成jar包:original-hibernate_spring_executable-0.0.1-SNAPSHOT.jar和hibernate_spring_executable-0.0.1-SNAPSHOT.jar,不用管original-hibernate_spring_executable-0.0.1-SNAPSHOT.jar,
(4)此时还要删除jar包中的META-INF\BCKEY.DSA,否则报错:
Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

注意:
(a)打成jar包后,需要把spring的配置文件拷贝到jar包同级目录,所以读取spring配置文件使用FileSystemXmlApplicationContext,而不是ClassPathXmlApplicationContext
(b)jdbc.properties也在jar同级目录,所以需要修改beans.xml中org.springframework.beans.factory.config.PropertyPlaceholderConfigurer配置,去掉classpath:.
(c)其实在生成的jar包中也有一份beans.xml,dao.xml.jdbc.properties,
做上述的修改(蓝色标记)只是为了让jar读取文件系统(与jar同级目录)中的配置文件,而不是jar包里面的配置文件.
