tomcat部署戰爭中的資源包未按預期作業-有解無憂

我遇到了一個與加載資源包相關的奇怪問題。經過一些除錯，我能夠找出問題的原因，因為資源包正在按預期順序加載。但是，我查詢是什么原因造成的。我有如下命名的資源包。

core_cs.properties
core_de.properties
core_en_GB.properties
core_en_US.properties
core_en.properties
core_fr.properties

當資源包通過 spring 配置加載時，基本名稱應該是

../core
../core_en

但是，這導致

../core_en
../core

因此，每個語言環境都顯示來自 core_en 資源包的翻譯值。在專案中，我在我的 Web 專案中添加 core.jar 作為依賴項。

當前行為。

我正在使用PathMatchingResourcePatternResolverspringframework 從類路徑配置中決議路徑

    <bean id="messageSource" class="com.company.core.spring.support.ClasspathResourceBundleMessageSource">
        <property name="basename" value="classpath*:/META-INF/resourcebundles/**/*.properties"/>  
    </bean>

ClasspathResourceBundleMessageSource是ResourceBundleMessageSource從springframework擴展而來的

public void setBasenames(final String... basenames) {
        List<String> basenamesList = new ArrayList<>();
        try {

            for (String basename : basenames) {
                LOGGER.info("==\t Base Name configured {}", basename);
                Resource[] resources = (new PathMatchingResourcePatternResolver()).getResources(basename);
                for (Resource resource : resources) {
                    LOGGER.info("==\t Name of resource found {}", resource.getURI());
                    String filename = resource.getURI().toString();
                    String newBasename = transformToBasename(filename);
                    if (newBasename != null && !basenamesList.contains(newBasename)) {
                        LOGGER.info("Adding resource bundle basename {}", newBasename);
                        basenamesList.add(newBasename);
                    }
                }
            }

            // Add the basenames found
            LOGGER.info("Resource bundle path:{}", basenamesList);
            String[] basenamesArray = basenamesList.toArray(new String[]{});
            super.setBasenames(basenamesArray);
        } catch (Exception ex) {
            LOGGER.error("Error setting base names", ex);
        }
    }

Another insight is that, if i build archive war locally it works. But, when archive is build by build server (jenkins), then it is not working as expected.

uj5u.com熱心網友回復：

我發現該JarFile.entries()方法 fromjava.util.jar.JarFile以未排序的順序回傳檔案串列。我用一個小程式對其進行了測驗。

import java.io.File;
import java.io.IOException;
import java.util.Enumeration;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class JarFileTest {

    public static void main(String[] args) {

        File correctJarFile = new File("D:\\target\\budget.jar");
        File wrongJarFile = new File("D:\\target\\budget2.jar");
     
        try (JarFile jar = new JarFile(correctJarFile )) {
            for (Enumeration<JarEntry> entries = jar.entries(); entries.hasMoreElements(); ) {
                JarEntry entry = entries.nextElement();
                String entryPath = entry.getName();
                if (entryPath.endsWith(".properties")) {
                    System.out.println(entryPath);
                }
            }
        }catch (IOException e) {
        }
        System.out.println("\n============ 2");
        try (JarFile jar = new JarFile(wrongJarFile)) {
            for (Enumeration<JarEntry> entries = jar.entries(); entries.hasMoreElements(); ) {
                JarEntry entry = entries.nextElement();
                String entryPath = entry.getName();
                if (entryPath.endsWith(".properties")) {
                    System.out.println(entryPath);
                }
            }
        }catch (IOException e) {
        }
    }
}

上面的程式導致下面的輸出。

META-INF/resourcebundles/core_cs.properties
META-INF/resourcebundles/core_de.properties
META-INF/resourcebundles/core_en.properties
META-INF/resourcebundles/core_en_GB.properties
META-INF/resourcebundles/core_en_US.properties
META-INF/resourcebundles/core_fr.properties

============ 2
META-INF/resourcebundles/core_en_GB.properties
META-INF/resourcebundles/core_cs.properties
META-INF/resourcebundles/core_de.properties
META-INF/resourcebundles/core_fr.properties
META-INF/resourcebundles/core_en_US.properties
META-INF/resourcebundles/core_en.properties

這與 Java8 Stream API 相同

        try (JarFile jar = new JarFile(jarFile)) {
            jar.stream().filter(entry -> entry.getName().endsWith(".properties")).forEach(System.out::println);
        } catch (IOException e) {
        }
        System.out.println("\n============ 0");
        try (JarFile jar = new JarFile(jarFile2)) {
            jar.stream().filter(entry -> entry.getName().endsWith(".properties")).forEach(System.out::println);
        } catch (IOException e) {
        }

因此，我已應用自定義排序來修復 ZipFile 中的排序問題，如此 stackoverflow 問題中所述
