如何調(diào)用其他對(duì)象的成員
接上文例子：
現(xiàn)在Person有一個(gè)屬性 name 靜態(tài)屬性 eye 域 gender
public class Person
{
public string name { get; set; }
public static object eye { get; set; }
public string gender;
public Pet pet { get; set; }public object seefrisbee(object color)
{
return string.Format("{0}看到{1}追著{2}顏色的飛盤", name,pet.name,color);
}
~Person()
{
Console.WriteLine(name + "離開");
}
}
對(duì)屬性賦值：
<object id="person" type="SpringDemo.Person,SpringDemo" singleton="true" >
<property name="pet" ref="dog" ></property>
<property name="name" value="Yahue"></property>
<property name="gender" value="男"></property>
<property name="eye" value="擁有迷離而又憂郁的眼神"></property>
<listener event="frisbeefly" method="seefrisbee">
<ref object="dog"/>
</listener>
</object>
name
<object id="personname" type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">
<property name="TargetObject" ref="person"></property>
<property name="TargetProperty" value="name"></property>
</object>eye
<!--靜態(tài)屬性的調(diào)用-->
<object id="personeye" type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">
<property name="StaticProperty" value="SpringDemo.Person.eye"></property>
</object>gender
<object id="persongender" type="Spring.Objects.Factory.Config.FieldRetrievingFactoryObject, Spring.Core">
<property name="TargetObject" ref="person"/>
<property name="TargetField" value="gender"/>
</object>執(zhí)行：
Console.WriteLine(ctx.GetObject("personname"));
Console.WriteLine(ctx.GetObject("persongender"));
Console.WriteLine(ctx.GetObject("personeye"));
Console.ReadLine();輸出結(jié)果：
調(diào)用其他對(duì)象的方法：
Person有了靜態(tài)say的方法：
public class Person
{
public string name { get; set; }
public static object eye { get; set; }
public string gender;
public Pet pet { get; set; }
public static string say(string word1,string word2,string word3)
{
return string.Format("說：{0}-{1}-{2}", word1, word2, word3);
}
public object seefrisbee(object color)
{
return string.Format("{0}看到{1}追著{2}顏色的飛盤", name,pet.name,color);
}
~Person()
{
Console.WriteLine(name + "離開");
}
}
xml
<object id="personsay" type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">
<property name="TargetType" value="SpringDemo.Person,SpringDemo"></property>
<property name="TargetMethod" value="say"></property>
<property name="Arguments">
<list>
<value>啊</value>
<value>大海啊</value>
<value>全是水</value>
</list>
</property>
</object>
Console.WriteLine(ctx.GetObject("personsay"));輸出：
說：啊-大海啊-全是水
現(xiàn)在有個(gè)非靜態(tài)的say2方法：
public class Person
{
public string name { get; set; }
public static object eye { get; set; }
public string gender;
public Pet pet { get; set; }
public static string say(string word1,string word2,string word3)
{
return string.Format("說：{0}-{1}-{2}", word1, word2, word3);
}
public string say2(string word1, string word2, string word3)
{
return string.Format("說：{0}-{1}-{2}", word1, word2, word3);
}
public object seefrisbee(object color)
{
return string.Format("{0}看到{1}追著{2}顏色的飛盤", name,pet.name,color);
}
~Person()
{
Console.WriteLine(name + "離開");
}
}
<object id="personsay2" type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">
<property name="TargetObject" ref="person"></property>
<property name="TargetMethod" value="say2"></property>
<property name="NamedArguments">
<dictionary>
<entry key="word1" value="啊！"></entry>
<entry key="word2" value="大海??！"></entry>
<entry key="word3" value="全是水！"></entry>
</dictionary>
</property>
</object>
注意ref的值是待調(diào)用對(duì)象的實(shí)例
調(diào)用：
Console.WriteLine(ctx.GetObject("personsay2"));執(zhí)行結(jié)果：
說：??！-大海?。?全是水！
注意：方法參數(shù)的傳遞有兩種方式：NamedArguments和Arguments 前者方法名和值是個(gè)鍵值，后者是個(gè)注入的參數(shù)順序和方法的參數(shù)順序?qū)?yīng)的集合。
