From fb4b70abdbf1ca93c86275dfb28fda46da7751cf Mon Sep 17 00:00:00 2001 From: WangTingZheng <2251985371@qq.com> Date: Tue, 14 Jul 2020 13:23:56 +0800 Subject: [PATCH] =?UTF-8?q?fix:=20=E4=BF=AE=E6=AD=A3=E6=89=BE=E4=B8=8D?= =?UTF-8?q?=E5=88=B0action=E7=9A=84=E9=97=AE=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 原因：struct.xml的位置不正确，不应该放在外面的（根目录）src里而是需要在web模块下新建一个src文件夹，把它标记为source 文件夹，然后把所有的Java包和struct.xml文件移动到这个目录下 修正： 1.在web模块下新建一个src文件夹并标记为source root 2.移动/src/guoyachen到/web/src/guoyachen 3.移动/src/struct.xml到/web/src/struct.xml 4.在file-project structure下的artifact里，在web-inf下新建lib文件夹存放jar包，右键点击avaliable elements下的条目，选择put into output root，记住，如果发现有找不到class的报错，重复次步骤即可，同时清除web-inf页面下的lib文件夹里有标红的jar 5.在file-project structure下的facets选项中，选择struct2，在右边点击铅笔图标，重新选择struct.xml的位置，具体的看这篇文章：https://www.jianshu.com/p/3a2ca7ee6b82 6.在pom.xml下条件build模块，强行规定jdk版本为1.8，修复由于依赖变动导致的jdk版本的错乱 7.添加${pageContext.request.contextPath}/到register.jsp下的action地址上 --- .../WebPage_Client_Test_war_exploded.xml | 20 ++++++ .idea/compiler.xml | 2 +- WebPage_Client_Test.iml | 10 +-- pom.xml | 16 +++++ .../WebPage_Client_Test.kotlin_module | Bin 16 -> 0 bytes src/main/java/guoyachen/mvc/Register.java | 61 ----------------- src/main/java/guoyachen/mvc/dao/UserDAO.java | 12 ---- .../mvc/dao/implement/UserDAOImpl.java | 55 --------------- .../guoyachen/mvc/dao/proxy/UserDAOProxy.java | 39 ----------- .../guoyachen/mvc/dbc/DatabaseConnection.java | 37 ---------- .../guoyachen/mvc/factory/DAOFactory.java | 16 ----- .../guoyachen/mvc/servlet/LoginServlet.java | 64 ------------------ src/main/java/guoyachen/mvc/vo/User.java | 31 --------- .../guoyachen/spring/DemoApplication.java | 9 --- src/main/resources/applicationcontext.xml | 7 -- src/struts.xml | 20 ------ web/register.jsp | 3 +- 17 files changed, 45 insertions(+), 357 deletions(-) delete mode 100644 src/main/java/META-INF/WebPage_Client_Test.kotlin_module delete mode 100644 src/main/java/guoyachen/mvc/Register.java delete mode 100644 src/main/java/guoyachen/mvc/dao/UserDAO.java delete mode 100644 src/main/java/guoyachen/mvc/dao/implement/UserDAOImpl.java delete mode 100644 src/main/java/guoyachen/mvc/dao/proxy/UserDAOProxy.java delete mode 100644 src/main/java/guoyachen/mvc/dbc/DatabaseConnection.java delete mode 100644 src/main/java/guoyachen/mvc/factory/DAOFactory.java delete mode 100644 src/main/java/guoyachen/mvc/servlet/LoginServlet.java delete mode 100644 src/main/java/guoyachen/mvc/vo/User.java delete mode 100644 src/main/java/guoyachen/spring/DemoApplication.java delete mode 100644 src/main/resources/applicationcontext.xml delete mode 100644 src/struts.xml diff --git a/.idea/artifacts/WebPage_Client_Test_war_exploded.xml b/.idea/artifacts/WebPage_Client_Test_war_exploded.xml index c8984cf..c4a38d5 100644 --- a/.idea/artifacts/WebPage_Client_Test_war_exploded.xml +++ b/.idea/artifacts/WebPage_Client_Test_war_exploded.xml @@ -7,6 +7,26 @@ + + + + + + + + + + + + + + + + + + + + diff --git a/.idea/compiler.xml b/.idea/compiler.xml index 9ed0716..1d0532b 100644 --- a/.idea/compiler.xml +++ b/.idea/compiler.xml @@ -10,7 +10,7 @@ - + \ No newline at end of file diff --git a/WebPage_Client_Test.iml b/WebPage_Client_Test.iml index 4a07f57..5bde2c6 100644 --- a/WebPage_Client_Test.iml +++ b/WebPage_Client_Test.iml @@ -11,13 +11,14 @@ - - file://$MODULE_DIR$/src/struts.xml + file://$MODULE_DIR$/web/src/struts.xml + file://$MODULE_DIR$/web/src/struts.xml + jar://$MODULE_DIR$/web/WEB-INF/lib/struts2-core-2.5.22.jar!/struts-default.xml @@ -32,13 +33,14 @@ - + - + + diff --git a/pom.xml b/pom.xml index d6a9cd7..0a69b8d 100644 --- a/pom.xml +++ b/pom.xml @@ -9,6 +9,22 @@ 1.0-SNAPSHOT + + + + org.apache.maven.plugins + maven-compiler-plugin + 3.1 + + 1.8 + 1.8 + UTF-8 + + + + + + diff --git a/src/main/java/META-INF/WebPage_Client_Test.kotlin_module b/src/main/java/META-INF/WebPage_Client_Test.kotlin_module deleted file mode 100644 index a49347afef10a9b5f95305e1058ba36adec7d6dd..0000000000000000000000000000000000000000 GIT binary patch literal 0 HcmV?d00001 literal 16 RcmZQzU|?ooU|@t|0RRA102TlM diff --git a/src/main/java/guoyachen/mvc/Register.java b/src/main/java/guoyachen/mvc/Register.java deleted file mode 100644 index 3d43b1c..0000000 --- a/src/main/java/guoyachen/mvc/Register.java +++ /dev/null @@ -1,61 +0,0 @@ -package guoyachen.mvc;
