我正在尝试设置Dynamic Web Module 3.0,以便支持Java 6开发。每当我执行Maven > Update Project
时,我都会在eclipse的Problems选项卡中得到这个错误。
Dynamic Web Module 3.1 requires Java 1.7 or newer.
看起来好像什么都没有出错,但我肯定遗漏了什么,因为我总是收到这个错误。
下面是我的.settings/org.eclipse.wst.common.project.facet.core.xml的内容
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="jst.java"/>
<fixed facet="jst.web"/>
<installed facet="jst.java" version="1.6"/>
<installed facet="jst.web" version="3.0"/>
</faceted-project>
在eclipse中,我的Java编译器被正确地设置为1.6。在Project Facets选项卡中,Dynamic Web Module被正确地指定为V3.0,Java也显示为Project Facets下的1.6。
在我的pom.xml文件中,我也相应地设置了Java版本:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
顺便说一句,我还应该提到,我正在使用WebApplicationInitializer
进行纯Java构建,并且没有web.xml文件。
在我试图消除这个看似无关紧要的错误消息时,我非常感谢您的帮助。
编辑:添加了pom.xml内容

在我们的项目中,我们添加更改web.xml
根元素的声明,从:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
至:
<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_2_5.xsd"
version="2.5" >
可能Eclipse期望它满足不同的Servlet版本规范。在我们的例子中,我们也没有编译和运行时的问题。
Eclipse:在您的例子中,您没有使用web.xml文件,有以下pom的依赖项,这可能会混淆的maven插件:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
将其更改为"3.0.1“。(事实证明,WebApplicationInitializer需要"Servlet 3.0+环境“,而不是3.1+)

您可以将以下内容添加到pom.xml中:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
在Spring STS 3.6.3中工作:)

尝试将JRE/JDK版本更改为1.7。web项目模块不支持1.6。
