一、核心依赖
webapp 的依赖,大致分为三部分:基本的 spring 组件依赖、日志及测试组件、web组件依赖等。大致为:
<dependencies> <!-- 1.base spring dependency --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${version.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${version.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${version.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${version.springframework}</version> </dependency> <!-- 2.base logger and test dependency --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>${version.log4j}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${version.slf4j}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${version.slf4j}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${version.junit}</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${version.springframework}</version> <scope>test</scope> </dependency> <!-- 3.base web dependency --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${version.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${version.springframework}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${version.javax.servlet.api}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>${version.javax.servlet.jsp.api}</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.tutianer</groupId> <artifactId>common</artifactId> <version>${version.tutianer.common}</version> </dependency> </dependencies>
二、项目构建配置
项目构建常见的配置项主要是设置jdk版本和资源过滤。如下:
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<resources>
<resource>
<directory>${project.basedir}/src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</configuration>
</plugin>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${version.jetty}</version>
<configuration>
<httpConnector>
<port>8003</port>
</httpConnector>
</configuration>
</plugin>
</plugins>
</pluginManagement>
<finalName>v1</finalName>
</build>
其中finaleName表示 webapp 打包后的名字,作为默认的 web 项目,设置为 ROOT 可以直接在 tomcat 中使用。
三、属性配置
<profiles> <profile> <id>dev</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <config.logger.level>INFO</config.logger.level> <config.redis.server>127.0.0.1</config.redis.server> <config.redis.port>6379</config.redis.port> <config.redis.prefixKey>local_</config.redis.prefixKey> <config.db.driverClassName>com.mysql.jdbc.Driver</config.db.driverClassName> <config.db.url>jdbc:mysql://localhost:3306/dbname?characterEncoding=utf8&useUnicode=true&useSSL=false</config.db.url> <config.db.username>root</config.db.username> <config.db.password>123456</config.db.password> <config.domain>http://localhost:8002</config.domain> </properties> </profile> <profile> <id>prod</id> <properties> <config.logger.level>INFO</config.logger.level> <config.redis.server>127.0.0.1</config.redis.server> <config.redis.port>6382</config.redis.port> <config.redis.prefixKey>prod_</config.redis.prefixKey> <config.db.driverClassName>com.mysql.jdbc.Driver</config.db.driverClassName> <config.db.url>jdbc:mysql://localhost:3306/dbname?characterEncoding=utf8&useUnicode=true&useSSL=false</config.db.url> <config.db.username>username</config.db.username> <config.db.password>pwd</config.db.password> <config.domain>http://domain</config.domain> </properties> </profile> </profiles>
在常规开发中,一个常见问题是在本地开发、测试、生产等几个环境中来回切换需要手工修改各项配置,而 maven 的属性配置则很好的解决了这个问题。当项目构建配置中使用了maven-resources-plugin插件时,在测试或者打包时,会自动将属性中配置的值替换到maven-resources-plugin所指定的资源目录中。
需要注意的是,其中的数据库配置要用&做转义;而该项直接在 xml 文件中配置则不需要转义。
这里默认激活的是activeByDefault所在的配置节,在打包或者测试时激活其他配置需要加参数P 来指定激活的配置项:-Pprod
四、web 版本配置
由于 maven 的 archvetype 略微陈旧,创建的 webapp 会被设置为2.3版本,可以在配置文件中修改为2.5。配置文件是web 项目.setting 目录中的org.eclipse.wst.common.project.facet.core.xml 文件,将
<installed facet="jst.web" version="2.3"/>
修改为:
<installed facet="jst.web" version="2.5"/>
五、其余配置
其余诸如spring、web.xml 等配置信息。
