Spring4-ListFactoryBean的使用
1.创建Maven项目,项目名称springdemo28,如图所示
2.配置Maven,修改项目中的pom.xml文件,如图所示
3.pom.xml文件的内容如下
<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>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>
4.在src/main/java下创建实体Bean Forum,包名(com.mycompany.shequ.bean)如图所示
5.实体Bean Forum的内容如下
package com.mycompany.shequ.bean; import java.util.List; public class Forum { private int fid; private String name; private List<Object> lists; public int getFid() { return fid; } public void setFid(int fid) { this.fid = fid; } public String getName() { return name; } public void setName(String name) { this.name = name; } public List<Object> getLists() { return lists; } public void setLists(List<Object> lists) { this.lists = lists; } @Override public String toString() { return "{fid=>"+this.fid+",name=>"+this.name+"}"; } }
6.在src/main/resources下创建spring-bean.xml配置文件,如图所示
7.spring-bean.xml配置文件的内容如下
<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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <bean id="forum" class="com.mycompany.shequ.bean.Forum"> <property name="fid" value="http://www.mamicode.com/1"></property> <property name="name" value="http://www.mamicode.com/集合"></property> <property name="lists"> <bean class="org.springframework.beans.factory.config.ListFactoryBean"> <property name="targetListClass"> <value>java.util.ArrayList</value> </property> <property name="sourceList"> <list> <value>1</value> <value>yi</value> <value>one</value> </list> </property> </bean> </property> </bean> </beans>
8.在src/main/resources下创建核心配置文件applicationContext.xml,如图所示
9.核心配置文件applicationContext.xml的内容如下
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <import resource="bean/spring-bean.xml"/> </beans>
10.在src/test/java下创建测试文件AppTest,包名(com.mycompany.shequ.test)如图所示
11.测试文件AppTest的内容如下
package com.mycompany.shequ.test; import java.util.List; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.mycompany.shequ.bean.Forum; public class AppTest { @Test public void beanTest(){ ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); Forum forum = (Forum) context.getBean("forum"); List<Object> lists = forum.getLists(); for (Object object : lists) { System.out.println(object); } } }
12.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
