Question

我需要在index.jsp页面中显示内部版本号

<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8" />
<title>Title (build: BUILDNUMBER )
</head>

构建号可以由maven提供到* .properties文件中。读取* .properties文件并使用Spring显示属性的最佳方法是什么？

Answer 1

您可以将.properties文件作为本地化消息源加载（使用ResourceBundlerMessageSource），并使用<spring:message>或<fmt:message>在JSP中访问它：

src/main/resources/buildInfo.properties：

buildNumber=${buildNumber}

Roland Schneider建议将buildNumber暴露出来。

上下文配置：

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name = "basenames"><value>buildInfo</value></property>
    <!-- Or a comma separated list if you have multiple .properties files -->
</bean>

JSP文件：

Version: <spring:message code = "buildNumber" />

pom.xml：

<resources>
    <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
    </resource>
</resources>

Answer 2

以下是我使用maven + jstl完成它的方法，而忽略了Spring，因为它使它变得更复杂。

build.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<jsp:useBean id="dateValue" class="java.util.Date" />
<jsp:setProperty name="dateValue" property="time" value="${timestamp}" />
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Build info</title>
</head>
<body>
<table>
<tr>
    <td>Build time: </td>
    <td><fmt:formatDate value="${dateValue}" pattern="dd.MM.yyyy HH:mm:ss" /></td>
</tr>
<tr>
    <td>Build number: </td>
    <td>${buildNumber}</td>
</tr>
<tr>
    <td>Branch: </td>
    <td>${scmBranch}</td>
</tr>
</table>
</body>
</html>

Maven pom

<!-- plugin that sets build number as a maven property -->
<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>buildnumber-maven-plugin</artifactId>
  <version>1.1</version>
  <executions>
    <execution>
      <phase>validate</phase>
      <goals>
        <goal>create</goal>
      </goals>
      <configuration>
        <format>{0,date,yyDHHmm}</format>
        <items>
          <item>timestamp</item>
        </items>
      </configuration>
    </execution>
  </executions>
  <configuration>
    <format>{0,date,yyDHHmm}</format>
    <items>
      <item>timestamp</item>
    </items>
  </configuration>
</plugin>
<!-- war plugin conf to enable filtering for our file -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <webResources>
            <resource>
                <directory>src/main/webapp/</directory>
                <includes>
                    <include>build.jsp</include>
                </includes>
                <filtering>true</filtering>
                <targetPath>.</targetPath>
            </resource>
        </webResources>
    </configuration>
</plugin>

警告：资源过滤对.jsp文件不起作用。正如Pascal Thivent指出的那样（谢谢）index.jsp不是资源，而是属于webapp。

我不知道您问题的确切答案，但是当index.jsp文件被复制到目标目录时，您可以直接使用maven将buildnumber硬编码到index.jsp文件中。您只需要将一个变量插入index.jsp并配置maven-resource-plugin以启用过滤。

Maven配置（从pom.xml中提取）

<build>

    <!-- Enable Resource Filtering -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>

    <!-- Fetch the SVN build-number into var ${buildNumber} -->
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>buildnumber-maven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>validate</phase>
                    <goals>
                        <goal>create</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <doCheck>false</doCheck>
                <doUpdate>false</doUpdate>
            </configuration>
        </plugin>
    </plugins>

</build>
