Spring 注入枚举类型和日期类型

Cup类：

package Test201402;import java.util.Date;public class Cup {private Long num;private Color color;private Date generator_date;private Class<?> prop;public Cup() {}public Cup(Long num, Color color, Date generator_date) {super();this.num = num;this.color = color;this.generator_date = generator_date;}public Long getNum() {return num;}public void setNum(Long num) {this.num = num;}public Color getColor() {return color;}public void setColor(Color color) {this.color = color;}public Date getGenerator_date() {return generator_date;}public void setGenerator_date(Date generator_date) {this.generator_date = generator_date;}public Class<?> getProp() {return prop;}public void setProp(Class<?> prop) {this.prop = prop;}}

1、注入枚举类型

只要把枚举类型当成静态常量即可。

// java 类

package Test201402;public enum Color {red,blue,green,orange,white,black}

// 配置文件

<bean id="cup" class="Test201402.Cup"><property name="num" value="1"/><property name="color" value="red"/></property></bean>

2、注入日期类型

由于日期类型不是常规类型，需要通过java.text.DateFormat.parse()解析，或者通过重写spring熟悉方法。

①、利用工厂注入方式，通过java.text.DateFormat.parse()解析日期字符串

// 配置文件

<!-- 方式一:利用工厂注入方式，通过java.text.DateFormat.parse()解析日期字符串， --><bean id="dateFormat" class="java.text.SimpleDateFormat"><constructor-arg index="0" value="yyyy-MM-dd"/></bean><bean id="cup" class="Test201402.Cup"><property name="num" value="1"/><property name="color" value="red"/><property name="generator_date" ><bean factory-bean="dateFormat" factory-method="parse"><constructor-arg value="2014-02-10"/></bean></property></bean>

②、通过重写spring熟悉方法，首先需要继承PropertyEditorSupport类重写setAsText方法，然后配置xml如下

继承PropertyEditorSupport类：

package Test201402;import java.beans.PropertyEditorSupport;import java.text.DateFormat;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;public class MyCustomerEditor extends PropertyEditorSupport{private String format;public String getFormat() {return format;}public void setFormat(String format) {this.format = format;}@Overridepublic void setAsText(String text) throws IllegalArgumentException {DateFormat df = new SimpleDateFormat(format);try {Date date = df.parse(text);this.setValue(date);} catch (ParseException e) {e.printStackTrace();}}}

测试类：

package Test201402;import static org.junit.Assert.assertEquals;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;import org.junit.Before;import org.junit.Test;import Test201309.BaseTest;public class Test20140210 extends BaseTest{@Testpublic void testDate(){Cup cup = bf.getBean("cup",Cup.class);assertEquals(cup.getColor(),Color.red);assertEquals(cup.getNum(),1L);Calendar calendar = Calendar.getInstance();calendar.set(2014, 1, 10, 0, 0, 0);assertEquals(cup.getGenerator_date(),calendar.getTime());}@Beforepublic void init(){this.setBf("conf/config_20140210.xml");}}

// 配置文件

<bean id="cup" class="Test201402.Cup"><property name="num" value="1"/><property name="color" value="red"/><property name="generator_date" ><value>2014-02-10</value></property></bean><!-- 方式二：通过重写spring熟悉方法，首先需要继承PropertyEditorSupport类重写setAsText方法，然后配置xml如下--> <bean id="customDateEditor" class="org.springframework.beans.factory.config.CustomEditorConfigurer"><property name="customEditors"><map><entry key="java.util.Date"><bean class="Test201402.MyCustomerEditor"><property name="format" value="yyyy-MM-dd"/></bean></entry></map></property></bean>
