Windows下Spring源码编译

Windows下Spring源码编译

下载源码

spring-framework

编译

1. Spring README.md 中有编译源码的手册

Build from Source

1. 编译命令 ./gradlew build spring脚本中会自动下载gradle并且执行剩余的编译动作

编译中的问题

在windows中编译会出现几个问题

1. 堆内存不足

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':referencePdf'.
GC overhead limit exceeded

GC overhead limit exceeded : 说明GC有98%的时间在处理垃圾回收 需要增加java内存

解决方法
修改gradlew.bat中 GRADLE_OPTS 参数设置(按照个人情况设置,不必要设置这么大)

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

1. 文件未找到

FAILURE: Build failed with an exception.
* What went wrong:
Failed to capture snapshot of input files for task 'distZip' during up-to-date check.
 java.io.FileNotFoundException: D:\git\spring-framework\build\distributions\spring-framework-4.3.11.BUILD-SNAPSHOT-schema.zip (The system cannot find the file specified)...

linux 和windows 的区别导致查找文件时没有找到spring-framework-4.3.11.BUILD-SNAPSHOT-schema.zip

解决方法
修改build.gradle中的schemaZip方法

task schemaZip(type: Zip) {
        group = "Distribution"
        baseName = "spring-framework"
        classifier = "schema"
        description = "Builds -${classifier} archive containing all " +
            "XSDs for deployment at http://springframework.org/schema."
        duplicatesStrategy 'exclude'
        moduleProjects.each { subproject ->
            def Properties schemas = new Properties();

            subproject.sourceSets.main.resources.find {
                it.path.endsWith("META-INF/spring.schemas")
            }?.withInputStream { schemas.load(it) }

            for (def key : schemas.keySet()) {
                def shortName = key.replaceAll(/http.*schema.(.*).spring-.*/, '$1')
                assert shortName != key
                File xsdFile = subproject.sourceSets.main.resources.find {

                    it.path.endsWith(schemas.get(key))
                }
                assert xsdFile != null
                into (shortName) {
                    from xsdFile.path
                }
            }
        }
    }

替换为

task schemaZip(type: Zip) {
        group = "Distribution"
        baseName = "spring-framework"
        classifier = "schema"
        description = "Builds -${classifier} archive containing all " +
            "XSDs for deployment at http://springframework.org/schema."
        duplicatesStrategy 'exclude'
        moduleProjects.each { subproject ->
            def Properties schemas = new Properties();

            subproject.sourceSets.main.resources.find {
            //这的路径需要改为\\
                it.path.endsWith("META-INF\\spring.schemas")
            }?.withInputStream { schemas.load(it) }

            for (def key : schemas.keySet()) {
                def shortName = key.replaceAll(/http.*schema.(.*).spring-.*/, '$1')
                assert shortName != key
                File xsdFile = subproject.sourceSets.main.resources.find {
                    //这里需要进行路径替换
                    it.path.endsWith(schemas.get(key).replaceAll('\\/','\\\\'))
                }
                assert xsdFile != null
                into (shortName) {
                    from xsdFile.path
                }
            }
        }
    }

1. test过不去

* What went wrong:
Execution failed for task ':spring-context-support:test'.
There were failing tests. See the report at: file:///D:/git/spring-framework/spring-context-support/build/reports/tests/index.html

打开提示的html发现有几条失败的test, 将提示错误的test中方法忽略或者删除

对JasperReportsUtils的test
JasperReportsUtils API介绍是 : 为CSV，HTML，PDF和XLS格式的报告提供了一套便利的方法.
对我们学习Spring源码没有影响

导入eclipse

虽然现在提倡使用idea,但是笔者还是习惯使用eclipse

1. 转换为eclipse项目命令
   还是Srping提供的手册中

./import-into-eclipse.bat

转换为eclipse项目分5个步骤
1). 提示将要转换的项目需要 Eclipse + AJDT 推荐使用STS
2). 提示转换需要用到Gradle,第一次使用会下载
3). 提示将项目导入eclipse/STS

File > Import... > Existing Projects into Workspace
       > When prompted for the 'root directory', provide %CURRENT_DIR%
       > Press enter. You will see the modules show up under "Projects"
       > All projects should be selected/checked. Click Finish.
       > When the project import is complete, you should have no errors.

4). 生成Spring根目录文件
5). 按照步骤2再次导入根文件
6). 完成,提示连接github(IDE已经自动连接了)

1. 添加eclipse支持Groovy的插件
   由于源码中有Groovy的文件,需要安装插件
   groovy for eclipse

在Wiki中找到Snapshot Builds,下载自己eclipse版本对应的Groovy插件

最后

至此Spring的源码已经完成编译,可以进行开发及学习
