• Ⅲ.spring的点点滴滴--赋值


    承接上文

    对象的赋值(调用方式都一样不再阐述)


    .net篇(环境为vs2012+Spring.Core.dll v1.31

    public class PropertyDemo{
       public System.Collections.ArrayList PropertyList { get; set; }
       public System.Collections.Specialized.HybridDictionary PropertyDictionary { get; set; }
       public System.Collections.Specialized.NameValueCollection PropertyNameValue { get; set; }
       public Spring.Collections.Set PropertySet { get; set; }
       public System.Collections.Generic.List<string> PropertyStrList { get; set; }
       public System.Collections.Generic.Dictionary<string, string> PropertyStrDictionary { get; set; }
       public string this[int index]  {
          get { return (string)PropertyList[index]; }
          set { PropertyList[index] = value; }
       } 
       public string this[string keyName] {
          get { return (string)PropertyDictionary[keyName]; }
          set { PropertyDictionary.Add(keyName, value); } 
       }
       public DateTime PropertyTime { get; set; }
    }
     <object name="PropertyDemo" type="SpringBase.PropertyDemo,SpringBase">
        <property name="PropertyList">
          <list>
            <value>a list element followed by a reference</value>
          </list>
        </property>
        <property name="PropertyDictionary">
          <dictionary>
            <entry key="a string => string entry" value="just some string"/>
          </dictionary>
        </property>
        <property name="PropertyNameValue">
          <name-values>
            <add key="HarryPotter" value="The magic property"/>
            <add key="JerrySeinfeld" value="The funny (to Americans) property"/>
          </name-values>
        </property>
        <property name="PropertySet">
          <set>
            <value>just some string</value>
          </set>
        </property>
        <property name="PropertyStrList">
          <list element-type="string">
            <value>a</value>
            <value>b</value>
            <value>c</value>
          </list>
        </property>
        <property name="PropertyStrDictionary">
          <dictionary key-type="string"  value-type="string">
            <entry key="zero">
              <value>jerry</value>
            </entry>
            <entry key="one">
              <value>Month</value>
            </entry>
            <entry key="two">
              <value>Nikola Tesla</value>
            </entry>
            <entry key="three">
              <value>DateTime.Today</value>
            </entry>
          </dictionary>
        </property>
        <property name="[0]" value="Master Shake"/> 
        <property name="['one']" value="uno"/>
        <property name="PropertyTime" expression="DateTime.Today + 7"/>
      </object>

    上面的标签和csharp的类型需要对应或者用基类也可以, expression是表达式运行的时候会自动换行为响应的值,key-type设置是泛型属性key的类型, key-value设置是泛型属性值的类型,属性索引老版本可能不是这样的设置的


    java篇(环境为Maven+Jdk1.7+IntelliJ IDEA 12.1.4

    package springdemo;
    import java.util.ArrayList;
    import java.util.Map;
    import java.util.Set;
    public class PropertyDemo {
        private ArrayList propertyList;
        public ArrayList getPropertyList() {
            return propertyList;
        }
        public void setPropertyList(ArrayList propertyList) {
            this.propertyList = propertyList;
        }
        private Map propertyDictionary;
        public Map getPropertyDictionary() {
            return propertyDictionary;
        }
        public void setPropertyDictionary(Map propertyDictionary) {
            this.propertyDictionary = propertyDictionary;
        }
        private Set propertySet;
        public Set getPropertySet() {
            return propertySet;
        }
        public void setPropertySet(Set propertySet) {
            this.propertySet = propertySet;
        }
        private Properties  propertyprops;
        public Properties getPropertyprops() {
            return propertyprops;
        }
        public void setPropertyprops(Properties propertyprops) {
            this.propertyprops = propertyprops;
        }
    }
     <bean id="PropertyDemo" class="springdemo.PropertyDemo">
            <property name="propertyList">
                <list>
                    <value>a list element followed by a reference</value>
                </list>
            </property>
            <property name="propertyDictionary">
                <map>
                    <entry key="a string => string entry" value="just some string"/>
                </map>
            </property>
            <property name="propertySet">
                <set>
                    <value>just some string</value>
                </set>
            </property>
            <property name="propertyprops">
                <props>
                    <prop key="db">172.0.0.1</prop>
                    <prop key="name">myself</prop>
                </props>
            </property>
     </bean>

    不知道java东西少还是什么只有这些,因为java是伪泛型也不支持属性索引器, 因为没有文档都是参考c# 探索出java


    javaCsharp的共同点

    其中我们在标签里面还可以用ref | idref标签或者属性来通过id | name引用其他的对象, 许多标签的属性可以当作一个独立的标签,如下

    <entry key="myKey"> <value>hello</value></entry>

    java中必须要有set字段的方法,Csharp可以省略
