0x01 依赖环境
- 安装 JDK 1.8 ,并配置环境变量
- 安装 Gradle 4.4.1 ,并配置环境变量
- Git
- IntellJ IDEA
0x02 下载源码到本地,导入IDEA
- https://github.com/spring-projects/spring-framework
- 这里建议fork到自己仓库,便于翻看源码添加注释
0x03 构建编译顺序
- 1.直接导入IDEA
- 2.选择本地的gradle目录环境,点击完成
* Where: Build file 'D:\code\framework\spring-framework\spring-beans\spring-beans.gradle' line: 28 * What went wrong: A problem occurred evaluating project ':spring-beans'. > No such property: immutableValues for class: org.gradle.api.internal.tasks.DefaultTaskDependency 注释掉:spring-beans.gradle: 28, 29行
* Where: Build file 'D:\code\framework\spring-framework\spring-test\spring-test.gradle' line: 103 * What went wrong: A problem occurred evaluating project ':spring-test'. > Could not find method useJUnitPlatform() for arguments [spring_test_f5fp54pu50zhhzke93j1kdcu1$_run_closure4$_closure13@61e2341b] on task ':spring-test:testJUnitJupiter' of type org.gradle.api.tasks.testing.Te st. 注释掉:spring-test.gradle: 102-135行
- 2.将阿里云的库添加到build.gradle 151行
- 3.等待项目Jar包下载完
maven { url "http://maven.aliyun.com/nexus/content/groups/public" }
- 4.进入spring-core目录下,执行gradle build命令将spring-core项目打包,要不然cglib报错
0x04 构建异常合集
- Could not resolve io.spring.gradle:propdeps-plugin:0.0.9.RELEASE.

算法设计与实验题解
王晓东 / 电子工业 / 2006-9 / 46.00元
《算法设计与实验题解》是与普通高等教育“十一五”国家级规划教材《计算机算法设计与分析》(第2版)配套的辅助教材,对主教材中的全部习题做了解答或给出了解题思路提示,并对主教材的内容进行了扩展,有些主教材中无法讲述的较深入的主题以习题的形式展现出来。为了提高学生解决实际问题的能力,《算法设计与实验题解》还将主教材中的许多习题改造成算法实现题,要求学生设计出算法并上机实现。作者还结合精品课程建设,进行了......一起来看看 《算法设计与实验题解》 这本书的介绍吧!
