Spring 4.0 学习日记（3）--- Spring依赖注入方式

依赖注入的几种数据类型的注入方式

很简单 没啥说的 看代码就是了

package com.wow.StudentInfo;public class Address {    private String address;    public String getAddress() {        return address;    }    public void setAddress(String address) {        this.address = address;    }}

package com.wow.StudentInfo;import java.util.List;import java.util.Map;import java.util.Properties;import java.util.Set;public class StudentInfo {    private String name;    private String [] names;    private List<String> IDs;    private Map<String, String> teacherName;    private Set<String> hobbies;    private String wife;    private Properties pro;    private Address add;    public void setName(String name) {        this.name = name;        System.out.println("name="+name);    }    public void setNames(String[] names) {        this.names = names;        for (int i = 0; i < names.length; i++) {            System.out.println("names="+names[i]);        }    }    public void setIDs(List<String> iDs) {        this.IDs = iDs;        System.out.println("IDs="+IDs);    }    public void setTeacherName(Map<String, String> teacherName) {        this.teacherName = teacherName;        System.out.println("teacherName="+teacherName);    }    public void setHobbies(Set<String> hobbies) {        this.hobbies = hobbies;    }    public void setAdd(Address add) {        this.add = add;        System.out.println("add="+add.getAddress());    }    public void setWife(String wife) {        this.wife = wife;        System.out.println("wife="+wife);    }    public void setPro(Properties pro) {        this.pro = pro;        System.out.println("pro="+pro);    }    public void printInfo(){        System.out.println("Info Running");    }}

重点来了 beans.xml如何配置

package com.wow.StudentInfo;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class StuTest {    public static void main(String[] args) {        ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");        StudentInfo stu = (StudentInfo)context.getBean("stu");    }}
