[自編號1-2]將spring framework源碼導入Spring Tool Suite中

阿新 • • 發佈：2018-01-27
4.0 1.8 比較 簡單 成了 valid 問題 wildcard declare

先講基本步驟，如下：

  1. 去GitHub中下載spring framework的源碼，https://github.com/spring-projects/spring-framework/releases
  2. 下載3.2.X其中的一個版本;
  3. 安裝Gradle軟件，官網下載，解壓即可，設置GRADLE_HOME,和PATH。
  4. 命令行中運行gradle -v，檢查一下是否正確安裝配置；
  5. 命令行中運行spring framework根目錄下的import-into-eclipse.bat
  6. 連續兩次回車，就可以開始自動構建；
  7. 中間出現停止不前的情況裏，按ctrl+c終止，再運行就可以進行下去；
  8. 過程需要花些時間（幾個小時都有可能），視下載各種依賴jar包和dom文件的速度而定；
  9. 在Eclipse菜單File->import選擇General下面的Exsiting projects into workspace，這樣就導入完成了。

如果你按上述步驟能一次成功的話，那不僅是你運氣，而且RP極高。反正我沒有，而且還折騰了好多次才成功能。

問題有以下幾個：

  • 問題一：spring-framework-4.0.0.M3要用jdk1.8

如果你習憒於什麽都下最新版的，那麽你肯定想都沒想就下了spring-framework-4.0.0.M3，而且又那麽不好采，正好沒看README，那麽問題馬上就來了，直接報"-XX:MaxMetaspaceSize=1024m"及"could not create the java Virtual machine"的錯誤。

查看build.gradle和gradlew.bat中，可以找出原因：

build.gradle中：

Java代碼 技術分享圖片
  1. compileJava {
  2. sourceCompatibility=1.6
  3. targetCompatibility=1.6
  4. }
  5. compileTestJava {
  6. sourceCompatibility=1.8
  7. targetCompatibility=1.8
  8. }

可以看出這個版本的test代碼要求用1.8。

gradlew.bat中

Java代碼 技術分享圖片
  1. set GRADLE_OPTS=-XX:MaxMetaspaceSize=1024m -Xmx1024m -XX:MaxHeapSize=256m %GRADLE_OPTS%

其中-XX:MaxMetaspaceSize是1.8的寫法。

所以如果下載的是4.0的版本，最好把jdk也升級到1.8，要不就下載一下3.2.x的版本就好了。

  • 問題2：在build過程中，出現heap內存溢出情況

錯誤信息如下：

那就把gradlew.bat的內存設置調大一點，我做實驗時，機器的內存是8G、64位系統，直接使用

set GRADLE_OPTS=-XX:MaxPermSize=2048m -Xmx2048m -XX:MaxHeapSize=1024m %GRADLE_OPTS%

（我下載的是spring-framework-3.2.1.RELEASE版本，jdk1.7）

  • 問題3：gradle命令的使用

在spring源碼的根目錄下，提供gradlew.bat和

import-into-eclipse.bat這兩個命令，都可以build源碼，但如果使用前者就不會生成eclipse的環境需要的一些文件，如下圖所示：

另外，在使用import-into-eclipse.bat這個命令build時，可能會遇到一個問題，錯誤日誌如下：

從日誌中可以看出是在build spring-webmvc-tiles3項目時，生成eclipse的.classpath文件時出錯，打開其它正常導入的項目的.classpath看下這個文件包含了哪些信息，如打開spring-aop項目的：

而spring-webmvc-tiles3下根本就沒有.classpath的影子，沒得比較，雖然上面的錯誤日誌的E文都認識，但還是看不出它在講什麽，不過大體能看得出是依賴出了問題，那只能是想辦法順藤摸瓜了。重新打開build.gradle，找到有關spring-webmvc-tiles3項目的描述，如下：

Java代碼 技術分享圖片
  1. project("spring-webmvc-tiles3") {
  2. description = "Spring Framework Tiles3 Integration"
  3. merge.into = project(":spring-webmvc")
  4. dependencies {
  5. provided(project(":spring-context"))
  6. provided(project(":spring-web"))
  7. provided("javax.el:el-api:1.0")
  8. provided("javax.servlet:jstl:1.2")
  9. provided("javax.servlet.jsp:jsp-api:2.1")
  10. optional("org.apache.tiles:tiles-request-api:1.0.1")
  11. optional("org.apache.tiles:tiles-api:3.0.1")
  12. optional("org.apache.tiles:tiles-core:3.0.1") {
  13. exclude group: "org.slf4j", module: "jcl-over-slf4j"
  14. }
  15. optional("org.apache.tiles:tiles-servlet:3.0.1") {
  16. exclude group: "org.slf4j", module: "jcl-over-slf4j"
  17. }
  18. optional("org.apache.tiles:tiles-jsp:3.0.1") {
  19. exclude group: "org.slf4j", module: "jcl-over-slf4j"
  20. }
  21. optional("org.apache.tiles:tiles-extras:3.0.1") {
  22. exclude group: "org.slf4j", module: "jcl-over-slf4j"
  23. }
  24. optional("org.apache.tiles:tiles-el:3.0.1") {
  25. exclude group: "org.slf4j", module: "jcl-over-slf4j"
  26. }
  27. provided("javax.servlet:javax.servlet-api:3.0.1")
  28. testCompile("org.slf4j:slf4j-jcl:${slf4jVersion}")
  29. }
  30. }

打開C:/Users/so/.gradle/caches/artifacts-15/filestore，挨個依賴進行檢查，jar包倒是最下載下來了，但是"org.apache.tiles:tiles-jsp:3.0.1"、"org.apache.tiles:tiles-extras:3.0.1"、"org.apache.tiles:tiles-el:3.0.1"三個卻沒有下載到source，其它包都有jar、pom、source三個目錄，這三個沒有source目錄，只有jar、pom目錄，問題應該是出現在這裏。

後來終於讓我找到了這麽一個東西：http://issues.gradle.org/browse/GRADLE-1157，正好證實我前面的猜想，所以按照issue中的解決辦法，在build.gradle中加上如下部分：

Java代碼 技術分享圖片
  1. eclipseClasspath {
  2. downloadSources = false; // required for eclipseClasspath to work
  3. }

關於spring-webmvc-tiles3項目的腳本、就變成這樣了：

重新運行命令，這一次終於讓我看到了BUILD SUCCESSFUL的字樣了……

成功build完成後，可以看到spring目錄下的spring-webmvc-tiles3項目也正常生成了導入eclipse需要的文件。打開.classpath查看一下：

Spring Tool Suite說簡單一點就是Spring家的eclipse，去官網下一個最新版，安裝上。

打開STS，菜單File->import選擇General下面的Exsiting projects into workspace，勾選要導入的子項目，確定即可。
