spring 和hibernate项目制作可执行的jar包

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:

jdbc.properties内容:

Java代码  

1. jdbc.driverClassName=oracle.jdbc.driver.OracleDriver  
2. jdbc.url=jdbc:oracle:thin:@localhost:1521:whuang  
3. jdbc.username=whuang  
4. 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

Java代码  

1. new ClassPathXmlApplicationContext("beans.xml", "dao.xml");  

 打成jar包的话,要改成:

Java代码  

1. new FileSystemXmlApplicationContext("beans.xml", "dao.xml");  

(2)修改beans.xml中读取jdbc.properties的方式

原来是:

Xml代码  

1. <bean  
2.         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
3.         <property name="locations">  
4.             <value>classpath:jdbc.properties</value>  
5.         </property>  
6.     </bean>  

 打成jar,就需要改为:

Xml代码  

1. <bean  
2.         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
3.         <property name="locations">  
4.             <value>jdbc.properties</value>  
5.         </property>  
6.     </bean>  

(3)maven中生成可执行jar的方式需要改maven plugin

原来使用

Xml代码  

1. <plugin>  
2.                 <artifactId>maven-assembly-plugin</artifactId>  
3.                 <configuration>  
4.                     <appendAssemblyId>false</appendAssemblyId>  
5.                     <descriptorRefs>  
6.                         <descriptorRef>jar-with-dependencies</descriptorRef>  
7.                     </descriptorRefs>  
8.                     <archive>  
9.                         <manifest>  
10.                             <mainClass>com.jn.NotepadApp</mainClass>  
11.                         </manifest>  
12.                     </archive>  
13.                 </configuration>  
14.                 <executions>  
15.                     <execution>  
16.                         <id>make-assembly</id>  
17.                         <phase>package</phase>  
18.                         <goals>  
19.                             <goal>assembly</goal>  
20.                         </goals>  
21.                     </execution>  
22.                 </executions>  
23.             </plugin>  

 打成jar,就需要改为:

Java代码  

1. <plugin>  
2.                 <groupId>org.apache.maven.plugins</groupId>  
3.                 <artifactId>maven-shade-plugin</artifactId>  
4.                 <version>1.4</version>  
5.                 <executions>  
6.                     <execution>  
7.                         <phase>package</phase>  
8.                         <goals>  
9.                             <goal>shade</goal>  
10.                         </goals>  
11.                         <configuration>  
12.                             <transformers>  
13.                                 <transformer  
14.                                     implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">  
15.                                     <mainClass><span style="font-size: 1em; line-height: 1.5;">com.jn.NotepadApp</span><span style="font-size: 1em; line-height: 1.5;"></mainClass></span>  
16.                                 </transformer>  
17.                                 <transformer  
18.                                     implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">  
19.                                     <resource>META-INF/spring.handlers</resource>  
20.                                 </transformer>  
21.                                 <transformer  
22.                                     implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">  
23.                                     <resource>META-INF/spring.schemas</resource>  
24.                                 </transformer>  
25.                             </transformers>  
26.                         </configuration>  
27.                     </execution>  
28.                 </executions>  
29.             </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

(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.
