为什么我的eclipse使用控制台输入java -version可以运行,输入javac就报告javac不是内部或外部命令?

我下载的是图片说明,然后我进行安装的目录是新建在D盘的JAVA目录下的JDK和JRE。
接着配置环境变量,步骤为图片说明图片说明图片说明。配置完成,也能正常的打开eclipse
但是控制台命令javac 失败

亲,环境变量里的path配好了吗,如果环境变量没有问题,那就可能是jdk和jre没有装好,这边建议你重新装一下

wu涛 谢谢你的回答,我弄了一下,重新打开eclipse,自动加载了一下,javac命令就可以运行了

%JAVA_HOME%\bin加入到Path里即可。

springboot项目 单库下,mybatis只需要添加如下配置,就可以打印sql语句 ```xml <!-- 打印查询语句 --> <setting name="logImpl" value="STDOUT_LOGGING" /> ``` 但是多库环境下,mybatis不论怎么设置,都无法打印sql语句..... ---- ---- 项目中的相关配置: mybatis配置: ```xml <!-- 设置运行参数 --> <settings> <!-- 全局映射器启用缓存 --> <setting name="cacheEnabled" value="true" /> <!-- 查询时,关闭关联对象及时加载以提高性能 --> <setting name="lazyLoadingEnabled" value="false" /> <!-- 设置关联对象加载的形态,此处为按需加载字段(加载字段由SQL指定),不会加载关联表的所有字段,以提高性能 --> <setting name="aggressiveLazyLoading" value="false" /> <!-- 对于位置的SQL查询,允许返回不同的结果集以达到通用的效果 --> <setting name="multipleResultSetsEnabled" value="true" /> <!-- 允许使用列标签代替列明 --> <setting name="useColumnLabel" value="true" /> <!-- 允许使用自定义的主键值(比如由程序生成的UUID 32位编码作为键值), 数据表的pk生成策略将被覆盖 --> <setting name="useGeneratedKeys" value="true" /> <!-- 给予被嵌套的resultMap以字段-属性的映射支持 --> <setting name="autoMappingBehavior" value="PARTIAL" /> <!-- 对于批量更新操作缓存SQL以提高性能 --> <setting name="defaultExecutorType" value="REUSE" /> <!-- 数据库超过25000秒仍未响应则超时 --> <!--<setting name="defaultStatementTimeout" value="25000" />--> <!-- 打印查询语句 --> <setting name="logImpl" value="STDOUT_LOGGING" /> <!-- 开启驼峰--> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> ``` logback配置: ```xml <?xml version="1.0" encoding="UTF-8"?> <configuration scan="true"> <!-- 属性1:每个logger都关联到logger上下文,默认上下文名称为“default”。

日志记录采用分级记录,级别与日志文件名相对应,不同级别的日志信息记录到不同的日志文件中 例如:error级别记录到log_error_xxx.log或log_error.log(该文件为当前记录的日志文件),而log_error_xxx.log为归档日志, 日志文件按日期记录,同一天内,若日志文件大小等于或大于2M,则按0、1、2...顺序分别命名 例如log-level-2013-12-21.0.log 其它级别的日志也是如此。 2、文件路径 若开发、测试用,在Eclipse中运行项目,则到Eclipse的安装路径查找logs文件夹,以相对路径../logs。 若部署到Tomcat下,则在Tomcat下的logs文件中 3、Appender FILEERROR对应error级别,文件名以log-error-xxx.log形式命名 FILEWARN对应warn级别,文件名以log-warn-xxx.log形式命名 FILEINFO对应info级别,文件名以log-info-xxx.log形式命名 FILEDEBUG对应debug级别,文件名以log-debug-xxx.log形式命名 CONSOLE将日志信息输出到控制上,为方便开发测试使用 --> <!-- 日志记录器,日期滚动记录 --> <appender

tomcat可以正常启动,但是在eclipse中只启动Tomcat报错,console控制台一行乱码
在tomcat的安装目录点击startup.bat可以正常运行,也可以访问。但是在eclipse中就出现如图所示的错误! ![图片说明](https://img-ask.csdn.net/upload/201904/28/1556442076_390544.png) ![图片说明](https://img-ask.csdn.net/upload/201904/28/1556442217_219047.png) 我的server.xml <?xml version="1.0" encoding="UTF-8"?> <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

Android模拟器无法启动,提示“invalid command-line parameter”
我在Eclipse中写了一个简单的“hello world”程序,我在java文件中什么都没有加,只在main.xml 中加了text view ,像下边这样: //main.xml文件 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Hello World" /> </LinearLayout> 当我运行我的程序的时候,它在控制台显示如下边的错误: //控制台输出 [2012-09-12 07:10:22 - demo] ------------------------------ [2012-09-12 07:10:22 - demo] Android Launch!

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
