.properties文件常量定义

application.properties文件，位于resources目录下。一般定义一些不会改变的数据如数据库相关配置，文件路径，项目地址。

如何在项目代码中获取该文件中的配置信息：

1，在applicationContext.xml中配置.properties中内容。

代码：

 <!--项目配置信息 -->
     <bean id="configInfo" class="com.pingan.credit.model.ConfigInfo">
         <property name="jks_name" value="${jks.name}"/>
         <property name="jks_password" value="123456"/>

         <property name="py_ssl_ip" value="${py.ssl.ip}"/>
         <property name="py_username" value="${py.username}"/>
         <property name="py_password" value="${py.password}"/>
         <property name="py_file_path" value="${py.filePath}"/>

         <property name="udmp_path" value="${udmp.path}"/>

         <property name="qhpdf_path" value="${qhpdf.path}"/>

         <property name="qh_rskdoo_url" value="${qh.rskdoo.url}"/>
         <property name="qh_loanee_url" value="${qh.loanee.url}"/>
         <property name="qh_antiFraudDoo_url" value="${qh.antiFraudDoo.url}"/>
         <property name="qh_eChkPkgs_url" value="${qh.eChkPkgs.url}"/>
         <property name="qh_address_url" value="${qh.address.url}"/>
         <property name="qh_ubzc2m_url" value="${qh.ubzc2m.url}"/>
         <property name="qh_creTrackInc_url" value="${qh.creTrackInc.url}"/>
         <property name="qh_creLBS_url" value="${qh.creLBS.url}"/>
         <property name="qh_eroticPerson_url" value="${qh.eroticPerson.url}"/>
         <property name="qh_credoo_url" value="${qh.credoo.url}"/>
         <property name="qh_eChkPkgsCard_url" value="${qh.eChkPkgsCard.url}"/>
         <property name="qh_xsCrtItgDataIdx_url" value="${qh.xsCrtItgDataIdx.url}"/>
         <property name="qh_orgCode" value="${qh.orgCode}"/>
         <property name="qh_chnlId" value="${qh.chnlId}"/>
         <property name="qh_authCode" value="${qh.authCode}"/>
         <property name="qh_username" value="${qh.username}"/>
         <property name="qh_password" value="${qh.password}"/>

         <property name="server_ip" value="${server.ip}"/>
     </bean>

2，在项目中定义实体，属性为applicationContext.xml文件中配置的属性信息

代码：

 @Component("configInfo")
 public class ConfigInfo {

     private String jks_name;

     private String py_ssl_ip;

     private String py_username;

     private String py_password;

     private String jks_password;

     private String udmp_path;

     private String qhpdf_path;

     private String qh_rskdoo_url;

     private String qh_loanee_url;

     private String qh_antiFraudDoo_url;

     private String qh_eChkPkgs_url;

     private String qh_address_url;

     private String qh_ubzc2m_url;

     private String qh_creTrackInc_url;

     private String qh_creLBS_url;

     private String qh_eroticPerson_url;

     private String qh_credoo_url;

     private String qh_eChkPkgsCard_url;

     private String qh_xsCrtItgDataIdx_url;

     private String qh_orgCode;

     private String qh_chnlId;

     private String qh_authCode;

     private String qh_username;

     private String qh_password;

     private String py_file_path;

     private String server_ip;

三,在项目中
注入调用
String pdfFilePath = configInfo.getPy_file_path() + "credit" + fileName + PDF_SUFFIX;
