1、maven項(xiàng)目在install時(shí)，報(bào)錯(cuò)

報(bào)錯(cuò)信息：

-Dmaven.multiModuleProjectDirectory system property is not set. Check $M2_HOME environment variable

解決方案

1.添加M2_HOME的環(huán)境變量
2.Preference->Java->Installed JREs->Edit 選擇一個(gè)jdk,
添加 -Dmaven.multiModuleProjectDirectory=$M2_HOME

-Dmaven.multiModuleProjectDirectory=$M2_HOME

2、eclipse啟動(dòng)慢卡

關(guān)閉不必要的啟動(dòng)項(xiàng)：window——Preferences——General——Startup and Shutdown 中，把Plug-ins activated on startup下面不用的都不要勾選。

eclipse.ini配置文件的修改（這個(gè)應(yīng)該懂吧）。

3、用maven創(chuàng)建不了項(xiàng)目

首先查看maven是否成功安裝以及配置
將生成的.m2文件刪掉，再創(chuàng)建項(xiàng)目（默認(rèn)路徑一般是：C:\Users\14065.m2）

4、maven編碼gbk不可映射字符

是由于Eclipse等編輯器與本地編碼格式不一致所導(dǎo)致。

安裝系統(tǒng)之后，一般中文系統(tǒng)默認(rèn)字符集是GBK。我們安裝的軟件一般都繼承使用操作系統(tǒng)的默認(rèn)字符集。所以當(dāng)在中文XP或者win7系統(tǒng)開發(fā)，在使用maven（mvn compile）編譯項(xiàng)目的時(shí)候，就會(huì)出現(xiàn)“編碼 gbk 的不可映射字符”：這個(gè)是由于代碼使用的UTF-8，而maven編譯的時(shí)候使用的GBK的緣故。可以通過修改項(xiàng)目的pom文件，可以告訴maven這個(gè)項(xiàng)目使用UTF-8編碼來編譯。在項(xiàng)目的pom.xml文件中添加下面的配置：

 <!-- 指明編譯源代碼時(shí)使用的字符編碼，maven編譯的時(shí)候默認(rèn)使用的GBK編碼， 通過project.build.sourceEncoding屬性設(shè)置字符編碼，告訴maven這個(gè)項(xiàng)目使用UTF-8來編譯 -->  
<properties>  
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  
</properties>

5、SpringMVC項(xiàng)目運(yùn)行時(shí)找不到DispatcherServlet映射

問題：

No mapping found for HTTP request with URI [/courses/view3] in DispatcherServlet with name 'mvc-dispatcher-servlet'

原因一：查看對(duì)應(yīng)的配置文件 mvc-dispatcher-servlet.xml 配置的路徑是否有誤

<!-- 確保此路徑無誤 -->
<context:component-scan base-package="com.xiao.mvcdemo">
    <context:include-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
</context:component-scan>

原因二：查看 web.xml 的配置是否有誤

<!-- DispatcherServlet, Spring MVC的核心 -->
  <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class> org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- DispatcherServlet對(duì)應(yīng)的上下文配置， 默認(rèn)為/WEB-INF/$servlet-name$-servlet.xml
         -->
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/configs/spring/mvc-dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <!-- mvc-dispatcher攔截所有的請(qǐng)求-->
        <url-pattern>/</url-pattern>
</servlet-mapping>

6、如何用maven下載源代碼

路徑：window——Preferences——Maven中：勾選Download Artifact Sources

Maven下載源碼

7、eclipse項(xiàng)目上初現(xiàn)紅叉

將所有的jar包重新導(dǎo)入，包括tomcat、jre。
可能是eclipse默認(rèn)使用的服務(wù)器不是你自己配置的，修改為自己配置的即可：右鍵項(xiàng)目——Properties——Targeted Runtimes 中選擇你自己的tomcat服務(wù)器（要仔細(xì)，比如系統(tǒng)默認(rèn)的是Apache Tomcat 7，而你自己的是Tomcat 7 Server）
更多類似問題參考

8、maven項(xiàng)目上有一個(gè)小紅叉

報(bào)錯(cuò)信息

Description Resource Path Location Type
Project configuration is not up-to-date with pom.xml. Run project configuration update rdc line 1 Maven Configuration Problem

解決方案

右鍵項(xiàng)目，【Maven】--》【Update Project Configuration...】即可

解決方案

8、普通java項(xiàng)目出現(xiàn)小紅叉

解決方案

右鍵項(xiàng)目——>properties——>project facets

解決方案

右鍵項(xiàng)目——>properties——>java Compiler

解決方案

9、修改maven的本地倉庫地址

配置為自己的maven地址

配置自己的本地倉庫

10、Eclipse智能提示沒用了

解決方案
- 1、window->Preferences->Java->Editor->content assist 把 Enable auto activation 選項(xiàng)打上勾：
  
  并且在點(diǎn)后面加上.abcdefghijklmnopqrstuvwxyz
  此時(shí)重啟了eclipse還不成功，之后接著第二步驟
- 2、window->Preferences->[Java] ->Editor->Content Assist->Advanced 把該勾選的斗勾選起來

自動(dòng)提示

11、Eclipse中創(chuàng)建maven web項(xiàng)目后報(bào)錯(cuò)

問題描述

web.xml is missing and <failOnMissingWebXml> is set to true

解決方案

在webapp目錄下創(chuàng)建"WEB-INF"，在"WEB-INF"下創(chuàng)建web.xml即可。

12、在啟動(dòng)maven項(xiàng)目時(shí)，報(bào)錯(cuò)Please ensure you are using JDK 1.4 or above and not a JRE

報(bào)錯(cuò)信息

Please ensure you are using JDK 1.4 or above and not a JRE

報(bào)錯(cuò)原因

eclipse默認(rèn)是使用jre作為運(yùn)行環(huán)境，而maven編譯需要jdk作為運(yùn)行環(huán)境

解決方案

window -> preferences -> Java -> installed jres，點(diǎn)擊add->選擇Standard VM，新加一個(gè)環(huán)境，設(shè)為默認(rèn)環(huán)境，注意location選擇為你的jdk目錄。

解決方案

如果還是不行，就在你的項(xiàng)目上右擊，build path -> configure build path，編輯JRE System Library，選擇剛才新建的默認(rèn)環(huán)境

13、tomcat啟動(dòng)maven項(xiàng)目報(bào)錯(cuò)：A child container failed during start

報(bào)錯(cuò)信息

嚴(yán)重: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].StandardContext[]]
...
嚴(yán)重: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost]]
...

報(bào)錯(cuò)原因

自己添加的 servlet.api包和tomcat的這個(gè)jar包沖突。

解決方案

刪掉servlet-api包

在該依賴的配置中添加<scope></scope>節(jié)點(diǎn)
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>

14、maven項(xiàng)目無法加載靜態(tài)的Xml，html，tsl

報(bào)錯(cuò)信息

嚴(yán)重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

錯(cuò)誤分析

此時(shí)，你可以去項(xiàng)目的工作空間里看看，你會(huì)驚訝的發(fā)現(xiàn)并沒有生成 .xml等文件，或者生成的.class，文件并不是和你編寫的.xml、.java源文件的文件內(nèi)容一致的，有可能你新加的一些方法或參數(shù)都不在其中，比如：我的BookEntityMapper.xml文件中的pojo引用為"com.ssm.frame.entity.BookEntity",但是在生成的BookEntityMapper.class文件中是"com.ssm.frame.entity.Book"等錯(cuò)誤。

是因?yàn)槟闶怯玫氖莔aven項(xiàng)目，maven項(xiàng)目都是依賴于jar配置，即依賴于pom.xml的配置，它不會(huì)自動(dòng)的為你加載靜態(tài).Xml，html，tsl 等文件，所以導(dǎo)致無法生成相應(yīng)的.class文件。

解決方案

<!--在pom.xml的build節(jié)點(diǎn)中加入以下配置-->
<resources>
            <resource>
                <directory>src/main/resources</directory>
