资源读取配置

2019独角兽企业重金招聘Python工程师标准>>>

第一步：建立资源文件

1.Messages.properties

vo.edit.msg = {0} \u4fe1\u606f\u7f16\u8bd1\u5b8c\u6210\uff01

2.Pages.properties

emp.add.page=/pages/back/emp/emp_add.jsp

3.Validations.properties

emp.add.rules=empno:int|ename:string|sal:double|hiredate:date

第二步：配置applicationContext-mvc.xml

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basenames">
	     <array>
	         <value>Messages</value>
	         <value>Pages</value>
	         <value>Validations</value>
	     </array>
	</property>
</bean>

第三步：父类中定义读取方法

package group.esperanto.action.util;

import java.text.SimpleDateFormat;
import java.util.Locale;
import javax.annotation.Resource;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.context.MessageSource;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;

public class AbstractAction {
	@Resource   //通过容器注入msgSource
    private MessageSource msgSource;
    // 定义读取资源文件内容   msgKey指properties文件中的键，args指传过来的参数，替代properties中的占位符
	public 	String getValue(String msgKey,Object...args){
		return this.msgSource.getMessage(msgKey, args, Locale.getDefault());
	}
}

第四步：控制器中读取

package group.esperanto.action;

import java.io.IOException;
import java.util.Date;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import javax.sound.midi.MidiDevice.Info;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import group.esperanto.action.util.AbstractAction;

@Controller
// 定义该Action的映射路径
// 该路径绝对不能重复
@RequestMapping("/pages/emp/*")
public class EmpAction extends AbstractAction {	
	private	Logger log = Logger.getLogger(EmpAction.class);
	@RequestMapping("info")
	public ModelAndView Info(){
		log.info(super.getValue("vo.edit.msg", "info "));
		log.info(super.getValue("emp.add.page"));
		log.info(super.getValue("emp.add.rules"));
		return null;
	}
	
}
