mybatis's Issues

pom.xml dependency problems

依赖问题

idea导入项目，好多插件依赖都找不到

如何联系项目管理者

您好，想咨询一下如果想提交PR，添加更详细的注释，如何联系项目管理者

org.apache.ibatis.io.ClassLoaderWrapper代码注释纠正

原文：
//defaultClassLoader没地方初始化啊?
ClassLoader defaultClassLoader;

我的：
/**

类加载器的包装类，通过类加载器读取资源
类加载器使用优先顺序：自定义类加载器，默认加载器，上下文类加载器，加载本类的类加载器，系统加载器{@link ClassLoaderWrapper#getClassLoaders(java.lang.ClassLoader)}
*/
public class ClassLoaderWrapper {

/**

默认类加载器通过{@link Resources#setDefaultClassLoader(java.lang.ClassLoader)}初始化
*/
ClassLoader defaultClassLoader;
}

// 通过Resource类的方法初始化
public static ClassLoader getDefaultClassLoader() {
return classLoaderWrapper.defaultClassLoader;
}

Run this program in "Intellij idea" ，There will be problems : Cause: java.lang.IllegalStateException: Cannot enable lazy loading because Javassist is not available. Add Javassist to your classpath

懒加载 setting属性lazyLoadTriggerMethods value错误

官网翻译setting示例为
<setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString"/>

按该方式配置不生效，需要在方法名后添加()表名这是一个方法，如下：
<setting name="lazyLoadTriggerMethods" c="equals(),clone(),hashCode(),toString()"/>

你好，我想问下，mybatis为何在多线程里面不生效。

mybatis导入Javassist依赖

mybatis导入Javassist依赖但是报错javassist.util.proxy.ProxyFactory

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)

按照文档教程调试一直报错
配置文件如下



打包之后显示文件正常

Is the cell or CELL belong to reserved words?

when the word cell or CELL in XML ,the result of response will be null。
if you replace cell to the other words,the result of response will be correct.

项目不更新了吗

test

为什么不将 mybatis-parent 的version 修改为可以由maven正常导入的版本，而还要进行手动导入呢

org.mybatis mybatis-parent 32 pom
