Spring各种类型数据的注入

直接上代码：

 

一个MessageBean类

 

 

package com.henu.spring;
import java.util.*;
public class MessageBean {

    private String username; //用户名
    private String fileDir;  //上传路径
    private Set<String> types;//允许上传类型
    private List<String> hbms;
    private Set<String> city;
    private Map<String, String> books;
    private Properties props;
    
    //注入一个字符串，分析之后给其赋值
    public void setTypes(String str){
        String[] arr = str.split(",");
        types = new HashSet<String>();
        for (String string : arr) {
            types.add(string);
        }
    }
    
    public void setUsername(String username) {
        this.username = username;
    }
    public void setFileDir(String fileDir) {
        this.fileDir = fileDir;
    }
    public void setCity(Set<String> city) {
        this.city = city;
    }
    public void setHbms(List<String> hbms) {
        this.hbms = hbms;
    }
    public void setBooks(Map<String, String> books) {
        this.books = books;
    }    
    public void setProps(Properties props) {
        this.props = props;
    }
    
    public void show(){
        System.out.println("用户名：" + username);
        System.out.println("上传路径" + fileDir);
        
        System.out.println("--hbm文件如下--");
        for (String string : hbms) {
            System.out.println(string);
        }
        
        System.out.println("--city如下--");
        for (String string : city) {
            System.out.println(string);
        }
        
        System.out.println("--图书信息显示--");
        Set set = books.keySet();
        for (Object object : set) {
            System.out.println(object+"   "+books.get(object));
        }
        
        System.out.println("--props参数如下--");
        Set<String> key = props.stringPropertyNames();
        Iterator<String> iterator = key.iterator();
        while(iterator.hasNext()){
            String string = (String) iterator.next();
            System.out.println(string+"   "+props.getProperty(string));
        }
        
        System.out.println("--允许上传文件类型--");
        for (String string : types) {
            System.out.println(string);
        }
    }
}

 

一个测试类

 

 

/**
 * 
 */
package com.henu.spring;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * @author Administrator
 *
 */
public class TestInjection {
    @Test
    public void test1(){
        ApplicationContext context = 
            new ClassPathXmlApplicationContext("/applicationContext.xml");
        MessageBean messageBean = (MessageBean) context.getBean("messageBean");
        messageBean.show();
    }
}

 

一个配置文件
