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  
    
  
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

   Java代码  
    
new ClassPathXmlApplicationContext("beans.xml", "dao.xml");

打成jar包的话,要改成:

   Java代码  
    
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  
    
  
<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:

   Xml代码  
    
  
<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

   Xml代码  
    
  
<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:

   Java代码  
    
  
<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><span style="font-size: 1em; line-height: 1.5;">com.jn.NotepadApp</span><span style="font-size: 1em; line-height: 1.5;"></mainClass></span>  
                                </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
