一，使用maven创建项目原型
mvn archetype:generate
进入交互模式创建项目原型，根据网速不同，跳出设置选项的时间不定
第一个选项
直接Enter即可，表示使用默认值502，后面的如法炮制，直到设置我们需要的groupId，artifactId，version为止。
我的设置为：
groupId：com.yxl.springdemo
artifactId：springdemo
version：1.0-SNAPSHOT（也就是默认值）
使用tree展示原型目录结构：
二，编辑源代码
首先创建一个bean类，在com/yxl/springdemo目录下新建HelloBean.java。
1 package com.yxl.springdemo; 2 3 public class HelloBean 4 { 5 private String helloword; 6 7 public void setHelloword(String helloword) 8 { 9 this.helloword = helloword; 10 } 11 public String getHelloword() 12 { 13 return helloword; 14 } 15 }
在com/yxl/springdemo目录下新建SpringDemo.java。
1 package com.yxl.springdemo; 2 3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5 import org.springframework.context.support.FileSystemXmlApplicationContext; 6 7 public class SpringDemo 8 { 9 public static void main(String[] args) 10 { 11 //ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-config.xml"); 12 ApplicationContext ctx = new FileSystemXmlApplicationContext("beans-config.xml"); 13 HelloBean hello = (HelloBean)ctx.getBean("helloBean"); 14 System.out.println(hello.getHelloword()); 15 } 16 }
重新编辑pom.xml，解决依赖关系，并生成可执行jar包。
1 <?xml version = "1.0" encoding = "UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/4.1.2.RELEASE1/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <modelVersion>4.0.0</modelVersion> 6 7 <groupId>com.yxl.springdemo</groupId> 8 <artifactId>springdemo</artifactId> 9 <version>1.0-SNAPSHOT</version> 10 <packaging>jar</packaging> 11 12 <name>springdemo</name> 13 <url>http://maven.apache.org</url> 14 15 <properties> 16 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 17 </properties> 18 19 <dependencies> 20 <dependency> 21 <groupId>org.springframework</groupId> 22 <artifactId>spring-core</artifactId> 23 <version>4.1.2.RELEASE</version> 24 </dependency> 25 <dependency> 26 <groupId>org.springframework</groupId> 27 <artifactId>spring-context</artifactId> 28 <version>4.1.2.RELEASE</version> 29 </dependency> 30 <dependency> 31 <groupId>org.springframework</groupId> 32 <artifactId>spring-context-support</artifactId> 33 <version>4.1.2.RELEASE</version> 34 </dependency> 35 <dependency> 36 <groupId>org.springframework</groupId> 37 <artifactId>spring-beans</artifactId> 38 <version>4.1.2.RELEASE</version> 39 </dependency> 40 <dependency> 41 <groupId>org.springframework</groupId> 42 <artifactId>spring-aop</artifactId> 43 <version>4.1.2.RELEASE</version> 44 </dependency> 45 <dependency> 46 <groupId>junit</groupId> 47 <artifactId>junit</artifactId> 48 <version>4.7</version> 49 <scope>test</scope> 50 </dependency> 51 </dependencies> 52 53 <build> 54 <plugins> 55 <plugin> 56 <groupId>org.apache.maven.plugins</groupId> 57 <artifactId>maven-shade-plugin</artifactId> 58 <version>2.3</version> 59 <executions> 60 <execution> 61 <phase>package</phase> 62 <goals> 63 <goal>shade</goal> 64 </goals> 65 <configuration> 66 <transformers> 67 <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> 68 <manifestEntries> 69 <Main-Class>com.yxl.springdemo.SpringDemo</Main-Class> 70 <Build-Number>123</Build-Number> 71 </manifestEntries> 72 </transformer> 73 </transformers> 74 </configuration> 75 </execution> 76 </executions> 77 </plugin> 78 </plugins> 79 </build> 80 81 </project>
在项目主目录springdemo（不是包目录）下新建beans-config.xml，配置bean属性。
1 <?xml version = "1.0" encoding = "UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://www.springframework.org/schema/beans 5 http://www.springframework.org/schema/beans/spring-beans.xsd"> 6 7 <bean id = "helloBean" 8 class = "com.yxl.springdemo.HelloBean"> 9 <property name = "helloword"> 10 <value>Hello, World</value> 11 </property> 12 </bean> 13 </beans>
在这里我犯过的一个错误就是xml文件第一行的?与xml之间插入了一个空格，然后运行程序就会抛出异常。
三，编译并运行结果
mvn clean compile mvn clean package java -jar target/sprintdemo-1.0-SNAPSHOT.jar
结果：
注意，执行java -jar target/springdemo-1.0-SNAPSHOT.jar时，配置文件必须在当前目录下。比如我是在项目根目录下执行这条语句，所以beans-config.xml也被放置在项目根目录springdemo中，如果在target中执行该包文件，执行时会抛出异常。
