intellij idea 使用的一些问题。

intellij在编译java项目的时候，同一个项目中有不同的模块，但是编译的时候一个模块编译成了class文件，另外的模块却没有编译。 第二个问题：intellij打开一个java文件，在编辑区默认的不是编辑模式，需要先按一下insert键才能编辑，有没有高手知道如何设置？求点播。

IntelliJ IDEA 2019.3.4 利用 Generate POJOs.groovy 生成 POJO 异常

我将 IDEA 版本升级到 2019.3.4 之后，利用 Generate POJOs.groovy 生成 POJO 时出现以下异常，不知大家有遇到过没？或者有什么解决思路可以分享下？ ``` Generate POJOs.groovy: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: Script21.groovy: 3: unable to resolve class com.intellij.database.util.DasUtil @ line 3, column 1. import com.intellij.database.util.DasUtil ^ Script21.groovy: 1: unable to resolve class com.intellij.database.model.DasTable @ line 1, column 1. import com.intellij.database.model.DasTable ^ Script21.groovy: 2: unable to resolve class com.intellij.database.util.Case @ line 2, column 1. import com.intellij.database.util.Case ^ 3 errors at org.codehaus.groovy.control.ErrorCollector.failIfErrors(ErrorCollector.java:309) at org.codehaus.groovy.control.CompilationUnit.applyToSourceUnits(CompilationUnit.java:981) at org.codehaus.groovy.control.CompilationUnit.doPhaseOperation(CompilationUnit.java:626) at org.codehaus.groovy.control.CompilationUnit.compile(CompilationUnit.java:575) at groovy.lang.GroovyClassLoader.doParseC...

intellij idea 13中web工程写了一个servlet

intellij idea 13中web工程写了一个servlet （里面写了一个输出语句） 启动服务器，为什么ie页面显示的是index.jsp内容，而不是servlet内容。 servlet写在YY.CLASS这个类里面： import javax.servlet.GenericServlet; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import java.io.IOException; /** * Created by ZHIYU on 2014/12/22. */ public class YY extends GenericServlet { @Override public void service(ServletRequest servletRequest, ServletResponse servletResponse) throws ServletException, IOException { servletResponse.getOutputStream().write("wwwwwwwwwwwwwwwwww".getBytes()); } } web.xml做了配置： <servlet> <servlet-name>YY</servlet-name> <servlet-class>YY</servlet-class> </servlet> <servlet-mapping> <servlet-name>YY</servlet-name> <url-pattern>/YY</url-pattern> </servlet-mapping> 不解为什么会这样 新手刚开始学 求热心人解答下
