Springでよく使われる構成

Springにセット属性を設定します.
二つのjavaファイルを作成します.

package com.cloud.peizhi;
public class Employee {
	private String name;
	private int id;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
}

package com.cloud.peizhi;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
public class Department {
	private String name;
	private String [] empName;
	private List<Employee> empList;
	private Set<Employee> empSet;
	private Map<String, Employee> empMap;
	private Properties pp;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String[] getEmpName() {
		return empName;
	}
	public void setEmpName(String[] empName) {
		this.empName = empName;
	}
	public List<Employee> getEmpList() {
		return empList;
	}
	public void setEmpList(List<Employee> empList) {
		this.empList = empList;
	}
	public Set<Employee> getEmpSet() {
		return empSet;
	}
	public void setEmpSet(Set<Employee> empSet) {
		this.empSet = empSet;
	}
	public Map<String, Employee> getEmpMap() {
		return empMap;
	}
	public void setEmpMap(Map<String, Employee> empMap) {
		this.empMap = empMap;
	}
	public Properties getPp() {
		return pp;
	}
	public void setPp(Properties pp) {
		this.pp = pp;
	}
}

テストファイルの作成

package com.cloud.peizhi;
import java.util.Properties;
import java.util.Map.Entry;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MyTest {
	/**
	 *   Spring        
	 */
	public static void main(String[] args) {
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		Department department = (Department) ac.getBean("department");
		System.out.println(department.getName());
		System.out.println("--------------------->String  ");
		for(String empName:department.getEmpName()){
			System.out.println(empName);

		System.out.println("--------------------->List  ");
		for(Employee e:department.getEmpList()){
			System.out.println(e.getName()+";"+e.getId());
		}

		System.out.println("--------------------->Properties");
		Properties pp = department.getPp();
		System.out.println(pp.get("pp1"));
		System.out.println(pp.get("pp2"));
	}
}

コンストラクタのプロパティを設定
javaクラスを作成

package com.cloud.peizhi;
public class Employee {
	private String name;
	private int id;
	public Employee(){
		System.out.println("      ！");
	}
	public Employee(String name){
		this.name = name;
		System.out.println("       ！");
	}
	public Employee(String name,int id){  
		System.out.println("         ");  
		this.name=name;  
		this.id=id;  
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
}

設定ファイル

<!--     2   ，    2         -->
<bean id="employee" class="com.cloud.peizhi.Employee">
	<constructor-arg index="0" type="java.lang.String" value="Spring"></constructor-arg>
	<constructor-arg index="1" type="int" value="23"></constructor-arg>
</bean>

テストファイル

package com.cloud.peizhi;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MyTest {
	/**
	 *   Spring        
	 */
	public static void main(String[] args) {
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		Employee employee = (Employee) ac.getBean("employee");
		System.out.println(employee.getName());
	}
}

継承属性の設定
javaファイルを作成する

package com.cloud.peizhi;
public class Student {
	private String name;
	private int age;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
}

package com.cloud.peizhi;
public class Gradate extends Student{
	private String degree;
	public String getDegree() {
		return degree;
	}
	public void setDegree(String degree) {
		this.degree = degree;
	}
}

プロファイルの作成

<!--        -->
<bean id="student" class="com.cloud.peizhi.Student">
	<property name="name" value="Spring"></property>
	<property name="age" value="22"></property>
</bean>
<!--   Gradate -->
<bean id="gradate" parent="student" class="com.cloud.peizhi.Gradate">
	<property name="name" value="summer"></property>
	<property name="degree" value="   "></property>
</bean>

試験種別の作成

package com.cloud.peizhi;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MyTest {
	/**
	 *   Spring

	public static void main(String[] args) {
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		Gradate gradate = (Gradate) ac.getBean("gradate");
		System.out.println(gradate.getName()+";"+gradate.getDegree());
	}
}
