建立Meaven项目(Meaven+SpringMvc)

1.选择建立Meaven Project项目





2.在列表里的Artifact Id里找到meaven-archetype-webapp





3.填写组名(Group Id)、组件名(Artifact Id)




4.引入Spring依赖包：在pom文件中引入以下特性



        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-test</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-core</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-oxm</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-tx</artifactId>

            <version>${srping.version}</version>

        </dependency>

          <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-jdbc</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-aop</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-context</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-context-support</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-expression</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-orm</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-web</artifactId>

            <version>${srping.version}</version>

        </dependency>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-webmvc</artifactId>

            <version>${srping.version}</version>

        </dependency>

这样我们就建立了一个MeavenWeb项目，但是建立后会出现各种报错，下面介绍一下常见报错的解决：

1.修改编码字符集:项目右键properties—Resource—Text file encoding选择自己需要的字符集





2.修改java版本:项目右键properties—java compiler修改版本

4000



3.引用本地java：在java bulidpath里的Library双击jre system library



4.Project Facets里面修改Dynamic web module为2.5的时候就会出现Cannot change version of project facet Dynamic web module to 2.5

(1)把web.xml的头改成

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

(2)修改项目的设置，在Navigator下打开项目.settings目录下的org.eclipse.jdt.core.prefs
eclipse.preferences.version=1  

org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled  

org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5  

org.eclipse.jdt.core.compiler.compliance=1.5  

org.eclipse.jdt.core.compiler.problem.assertIdentifier=error  

org.eclipse.jdt.core.compiler.problem.enumIdentifier=error  

org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning  

org.eclipse.jdt.core.compiler.source=1.5  

把1.5改成1.6

eclipse.preferences.version=1  

org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled  

org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.6  

org.eclipse.jdt.core.compiler.compliance=1.6  

org.eclipse.jdt.core.compiler.problem.assertIdentifier=error  

org.eclipse.jdt.core.compiler.problem.enumIdentifier=error  

org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning  

org.eclipse.jdt.core.compiler.source=1.6  

打开org.eclipse.wst.common.component

<?xml version="1.0" encoding="UTF-8"?>
 

<project-modules id="moduleCoreId" project-version="1.5.0">  

    <wb-module deploy-name="test">  

        <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>  

        <wb-resource deploy-path="/" source-path="/src/main/webapp" tag="defaultRootSource"/>  

        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>  

        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>  

        <property name="context-root" value="test"/>  

        <property name="java-output-path" value="/test/target/classes"/>  

    </wb-module>  

</project-modules>

把project-version="1.5.0"改成project-version="1.6.0"

<?xml
version="1.0" encoding="UTF-8"?>  

<project-modules id="moduleCoreId" project-version="1.6.0">  

    <wb-module deploy-name="test">  

        <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>  

        <wb-resource deploy-path="/" source-path="/src/main/webapp" tag="defaultRootSource"/>  

        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>  

        <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>  

        <property name="context-root" value="test"/>  

        <property name="java-output-path" value="/test/target/classes"/>  

    </wb-module>  

</project-modules>  

打开org.eclipse.wst.common.project.facet.core.xml

<?xml
version="1.0" encoding="UTF-8"?>  

<faceted-project>  

  <fixed facet="wst.jsdt.web"/>  

  <installed facet="java" version="1.5"/>  

  <installed facet="jst.web" version="2.3"/>  

  <installed facet="wst.jsdt.web" version="1.0"/>  

</faceted-project> 

把<installed
facet="java" version="1.5"/>改成<installed facet="java" version="1.6"/>，把  <installed facet="jst.web" version="2.3"/>改成  <installed facet="jst.web" version="2.5"/>

<?xml
version="1.0" encoding="UTF-8"?>  

<faceted-project>  

  <fixed facet="wst.jsdt.web"/>  

  <installed facet="java" version="1.6"/>  

  <installed facet="jst.web" version="2.5"/>  

  <installed facet="wst.jsdt.web" version="1.0"/>  

</faceted-project> 

都改好之后在打开看看，已经把Dynamic
web module改成了2.5
