spring 注入参数时为list map写法用例

导包基础：这了让服务器支持json 需要导入下面包

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.28</version>
</dependency>

这是一个基本类，++++++++++++++++++++++++++++++++++++++++++
package com.itheima.dao;

import java.lang.reflect.Array;
import java.util.*;

public class BookDaofff {
    private int[] array;
    private List<String> list;
    private Set<String> set;
    private Map<String, String> map;
    private Properties properties;

    public void setArray(int[] array){this.array = array;}
