复杂数据类型注入

创建一个Student对象

package com.huangxin.spring.model;
public class Student {
    private String name;
    private int age;
    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + 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;
    }
}

复杂数据

package com.huangxin.spring.model;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
public class CollectionBean {
    private List<String> list;
    private Set<String> set;
    private String array[] = new String[3];
    private Map<String, Object> map;
    private Properties properties;
    public List<String> getList() {
        return list;
    }
    public void setList(List<String> list) {
        this.list = list;
    }
    public Set<String> getSet() {
        return set;
    }
    public void setSet(Set<String> set) {
        this.set = set;
    }
    public String[] getArray() {
        return array;
    }
    public void setArray(String[] array) {
        this.array = array;
    }
    public Map<String, Object> getMap() {
        return map;
    }
    public void setMap(Map<String, Object> map) {
        this.map = map;
    }
    public Properties getProperties() {
        return properties;
    }
    public void setProperties(Properties properties) {
        this.properties = properties;
    }
}

以上为大部分数据的注入,仔细看配置
