1.创建Maven项目,项目名称springdemo45,如图所示
2.配置Maven,修改项目中的pom.xml文件,修改内容如下
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>1.0.0</modelVersion> <groupId>shequ</groupId> <artifactId>springdemo13</artifactId> <version>0.0.1-SNAPSHOT</version> <properties> <java.version>1.7</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> </properties> <repositories> <repository> <id>codelds</id> <url>https://code.lds.org/nexus/content/groups/main-repo</url> </repository> </repositories> <dependencies> <dependency> <groupId>javax.annotation</groupId> <artifactId>jsr250-api</artifactId> <version>1.0</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.1.4.RELEASE</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.4.RELEASE</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34</version> </dependency> </dependencies> <build/> </project>
3.在src/main/java下创建实体Bean Forum,包名(com.mycompany.shequ.bean)如图所示
4.实体Bean Forum的内容如下
package com.mycompany.shequ.bean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component("forumBean")
public class Forum {
private int fid;
private String name;
private int displayOrder;
public int getDisplayOrder() {
return displayOrder;
}
@Value("1")
public void setDisplayOrder(int displayOrder) {
this.displayOrder = displayOrder;
}
public int getFid() {
return fid;
}
@Value("1")
public void setFid(int fid) {
this.fid = fid;
}
public String getName() {
return name;
}
@Value("Spring EL以注解形式")
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "{fid=>"+this.fid+",name=>"+this.name+",displayOrder=>"+this.displayOrder+"}";
}
public String getAddress(String address){
return address;
}
}
5.在src/main/java下创建实体Bean ForumPost,包名(com.mycompany.shequ.bean)如图所示
6.实体Bean ForumPost的内容如下
package com.mycompany.shequ.bean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component("forumPostBean")
public class ForumPost {
private int pid;
private String name;
private Forum forum;
private String address;
public String getAddress() {
return address;
}
@Value("#{forumBean.getAddress('jiangsu')}")//通过.调用forumBean中的getAddress方法
public void setAddress(String address) {
this.address = address;
}
public int getPid() {
return pid;
}
@Value("1")
public void setPid(int pid) {
this.pid = pid;
}
public String getName() {
return name;
}
@Value("#{forumBean.name}")//通过.调用forumBean中的name属性
public void setName(String name) {
this.name = name;
}
public Forum getForum() {
return forum;
}
@Value("#{forumBean}")
public void setForum(Forum forum) {
this.forum = forum;
}
}
7.在src/main/resource下创建核心的配置文件applicationContext.xml,如图所示
8.核心的配置文件applicationContext.xml的内容如下
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <context:component-scan base-package="com.mycompany.shequ.bean"/> </beans>
9.在src/test/java下创建测试文件AppTest,包名(com.mycompany.shequ.test)如图所示
10.测试文件AppTest的内容如下
package com.mycompany.shequ.test;
import org.junit.Test;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mycompany.shequ.bean.ForumPost;
public class AppTest {
@Test
public void beanTest(){
ConfigurableApplicationContext context = new
ClassPathXmlApplicationContext("applicationContext.xml");
ForumPost forumPost = (ForumPost) context.getBean("forumPostBean");
System.out.println(forumPost.getName());
System.out.println(forumPost.getAddress());
System.out.println(forumPost.getForum());
}
}
11.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
