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"?>
<beans xmlns="http://www.springframework.org/schema/beans"

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

参考:http://hw1287789687.iteye.com/blog/2019501

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
