Spring Cloud - 开发环境搭建

1、JDK环境安装

1、下载jdk17：下载地址，在下图中红色框部分进行下载

2、双击安装，基本都是下一步直到完成。

3、设置系统环境变量：参考

4、设置JAVA_HOME环境变量

5、在PATH中添加%JAVA_HOME%/bin

6、在命令行中执行：java -version,如下图则安装成功

2、MAVEN环境

1、官网下载地址：maven

2、下载后解压到某个文件夹下

3、配置maven的环境变量

4、验证：mvn -v

3、安装Elicpse

1、下载地址：官网地址

2、解压到某个文件夹即可。

4、配置mvn的xml

注意：

1、该文件在开发环境不变的情况下，不建议每个项目一个，而是多个项目使用一个

2、下载文件较多，占用的磁盘比较大

配置步骤：

1、新建settings.xml，内容如下：

需要需改文件中的存储路径《E:\javaProject\repos》，根据个人需要修改

	It's normally provided in | ${maven.conf}/settings.xml. | | NOTE: This location 
	can be overridden with the CLI option: | | -gs /path/to/global/settings.xml 
	| | The sections in this sample file are intended to give you a running start 
	at | getting the most out of your Maven installation. Where appropriate, 
	the default | values (values used when the setting is not specified) are

		store artifacts. | | Default: ${user.home}/.m2/repository <localRepository>/path/to/local/repo</localRepository> -->

		Default: true <interactiveMode>true</interactiveMode> -->

	<!-- offline | Determines whether maven should attempt to connect to the 
		network when executing a build. | This will have an effect on artifact downloads, 
		artifact deployment, and others. | | Default: false <offline>false</offline> -->

	<!-- pluginGroups | This is a list of additional group identifiers that 
		will be searched when resolving plugins by their prefix, i.e. | when invoking

	<!-- servers | This is a list of authentication profiles, keyed by the server-id 
		used within the system. | Authentication profiles can be used whenever maven 
		must make a connection to a remote server. | -->
	<servers>
		<!-- server | Specifies the authentication information to use when connecting 
			to a particular server, identified by | a unique name within the system (referred 
			to by the 'id' attribute below). | | NOTE: You should either specify username/password 
			OR privateKey/passphrase, since these pairings are | used together. | <server>

	<!-- mirrors | This is a list of mirrors to be used in downloading artifacts 
		from remote repositories. | | It works like this: a POM may declare a repository 
		to use in resolving certain artifacts. | However, this repository may have 
		problems with heavy traffic at times, so people have mirrored | it to several 
		places. | | That repository definition will have a unique id, so we can create 
		a mirror reference for that | repository, to be used as an alternate download 
		site. The mirror site will be the preferred | server for that repository. 
		| -->
	<mirrors>
		<!-- mirror | Specifies a repository mirror site to use instead of a given 
			repository. The repository that | this mirror serves has an ID that matches 
			the mirrorOf element of this mirror. IDs are used | for inheritance and direct 
			lookup purposes, and must be unique across the set of mirrors. | <mirror> 
			<id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable 
			Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url>

	<!-- profiles | This is a list of profiles which can be activated in a variety 
		of ways, and which can modify | the build process. Profiles provided in the 
		settings.xml are intended to provide local machine- | specific paths and 
		repository locations which allow the build to work in the local environment. 
		| | For example, if you have an integration testing plugin - like cactus 
		- that needs to know where | your Tomcat instance is installed, you can provide 
		a variable here such that the variable is | dereferenced during the build 
		process to configure the cactus plugin. | | As noted above, profiles can 
		be activated in a variety of ways. One way - the activeProfiles | section 
		of this document (settings.xml) - will be discussed later. Another way essentially 
		| relies on the detection of a system property, either matching a particular 
		value for the property, | or merely testing its existence. Profiles can also 
		be activated by JDK version prefix, where a | value of '1.4' might activate 
		a profile when the build is executed on a JDK version of '1.4.2_07'. | Finally, 
		the list of active profiles can be specified directly from the command line. 
		| | NOTE: For profiles defined in the settings.xml, you are restricted to 
		specifying only artifact | repositories, plugin repositories, and free-form 
		properties to be used as configuration | variables for plugins in the POM. 
		| | -->
	<profiles>
		<!-- profile | Specifies a set of introductions to the build process, to 
			be activated using one or more of the | mechanisms described above. For inheritance 
			purposes, and to activate profiles via <activatedProfiles/> | or the command 
			line, profiles have to have an ID that is unique. | | An encouraged best 
			practice for profile identification is to use a consistent naming convention 
			| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 
			'user-brett', etc. | This will make it more intuitive to understand what 
			the set of introduced profiles is attempting | to accomplish, particularly 
			when you only have a list of profile id's for debug. | | This profile example 
			uses the JDK version to trigger activation, and provides a JDK-specific repo. 
			<profile> <id>jdk-1.4</id> <activation> <jdk>1.4</jdk> </activation> <repositories> 
			<repository> <id>jdk14</id> <name>Repository for JDK 1.4 builds</name> <url>http://www.myhost.com/maven/jdk14</url> 
			<layout>default</layout> <snapshotPolicy>always</snapshotPolicy> </repository> 
			</repositories> </profile> -->

		<!-- | Here is another profile, activated by the system property 'target-env' 
			with a value of 'dev', | which provides a specific path to the Tomcat instance. 
			To use this, your plugin configuration | might hypothetically look like: 
			| | ... | <plugin> | <groupId>org.myco.myplugins</groupId> | <artifactId>myplugin</artifactId> 
			| | <configuration> | <tomcatLocation>${tomcatPath}</tomcatLocation> | </configuration> 
			| </plugin> | ... | | NOTE: If you just wanted to inject this configuration 
			whenever someone set 'target-env' to | anything, you could just leave off 
			the <value/> inside the activation-property. | <profile> <id>env-dev</id> 
			<activation> <property> <name>target-env</name> <value>dev</value> </property> 
			</activation> <properties> <tomcatPath>/path/to/tomcat/instance</tomcatPath> 
			</properties> </profile> -->
	</profiles>

	<!-- activeProfiles | List of profiles that are active for all builds. | 
		<activeProfiles> <activeProfile>alwaysActiveProfile</activeProfile> <activeProfile>anotherAlwaysActiveProfile</activeProfile> 
		</activeProfiles> -->
</settings>
