服务器开发问题

问题：gradle下载缓慢

解决：使用阿里云仓库，在C:\Users\***\.gradle\wrapper\dists\gradle-6.4.1-bin\***\gradle-6.4.1\init.d这个目录下新建init.gradle文件，内容：

allprojects{

repositories {

def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public/'

def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/jcenter/'

def ALIYUN_GOOGLE_URL = 'https://maven.aliyun.com/repository/google/'

def ALIYUN_GRADLE_PLUGIN_URL = 'https://maven.aliyun.com/repository/gradle-plugin/'

all { ArtifactRepository repo ->

if(repo instanceof MavenArtifactRepository){

def url = repo.url.toString()

if (url.startsWith('https://repo1.maven.org/maven2/')) {

project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."

remove repo

}

if (url.startsWith('https://jcenter.bintray.com/')) {

project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."

remove repo

}

if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {

project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GOOGLE_URL."

remove repo

}

if (url.startsWith('https://plugins.gradle.org/m2/')) {

project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GRADLE_PLUGIN_URL."

remove repo

}

maven { url ALIYUN_REPOSITORY_URL }

maven { url ALIYUN_JCENTER_URL }

maven { url ALIYUN_GOOGLE_URL }

maven { url ALIYUN_GRADLE_PLUGIN_URL }

}

问题： eclipse javaee 不能生成在 WEB-INF/classes 中生成 .class文件，导致 class not found.

解决：右键项目》properties 》java build path 》修改缺省输出文件夹，改为WEB-INF/classes

问题：tomcat7 报 Java.lang.OutOfMemoryError：Metaspace 错误，重启 tomcat7 无效

解决：删除 tomcat7 目录下 work 文件夹，重启 tomcat7 。（清除了项目缓存）
