一、多行注释快捷键
1.选中你要加注释的区域，用 Ctrl+Shift+C 或者 Ctrl+/ 会加上 // 注释，再重复按一下就会去掉 // 注释。（.js文件中只有 Ctrl+Shift+C 管用，.java文件中都管用）
2.选中你要加注释的区域，用 Ctrl+shit+/ 会加上 /*...*/ 注释，再用 Ctrl+shit+\ 会去掉 /*...*/ 注释。（注意：正斜杠是加注释，反斜杠是去掉注释）
3.要修改在eclispe中的命令的快捷键方式我们只需进入 Windows -> Preferences -> General -> keys 设置就行。
二、Eclipse中添加文档注释快捷键
1.例如默认的文档注释：
/**
* @author xxx
*
*
*/
2.快捷键为：Alt+Shift+J
3.修改文档注释的注释格式内容，修改的方法有两种：
A.直接在eclipse给的模板下进行修改
打开Eclipse
Window --> Preferences --> Java --> Code Style --> Code Templates --> Comments --> types --> Edit...
例如：
/**
* 项目名称：${project_name}
* 类名称：${type_name}
* 类描述：
* 创建人：${user}
* 创建时间：${date} ${time}
* @version
*/
B.自己编写一个xml文档导入进去
打开Eclipse
Window --> Preferences --> Java --> Code Style --> Code Templates --> Comments --> types --> Import...
选择你写好的模板.xml文件
Eclipse中默认的模板.xml文件如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?><templates><template autoinsert="true" context="constructorcomment_context" deleted="false" description="Comment for created constructors" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.constructorcomment" name="constructorcomment">/** * ${tags} */</template><template autoinsert="false" context="typecomment_context" deleted="false" description="Comment for created types" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.typecomment" name="typecomment">/** * @author ${user} * * ${tags} */ </template><template autoinsert="true" context="fieldcomment_context" deleted="false" description="Comment for fields" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.fieldcomment" name="fieldcomment">/** * */</template><template autoinsert="true" context="settercomment_context" deleted="false" description="Comment for setter method" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.settercomment" name="settercomment">/** * @param ${param} the ${bare_field_name} to set */</template><template autoinsert="true" context="filecomment_context" deleted="false" description="Comment for created Java files" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.filecomment" name="filecomment">/** * */</template><template autoinsert="true" context="gettercomment_context" deleted="false" description="Comment for getter method" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.gettercomment" name="gettercomment">/** * @return the ${bare_field_name} */</template><template autoinsert="true" context="methodcomment_context" deleted="false" description="Comment for non-overriding methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.methodcomment" name="methodcomment">/** * ${tags} */</template><template autoinsert="true" context="delegatecomment_context" deleted="false" description="Comment for delegate methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.delegatecomment" name="delegatecomment">/** * ${tags} * ${see_to_target} */</template><template autoinsert="true" context="overridecomment_context" deleted="false" description="Comment for overriding methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.overridecomment" name="overridecomment">/* (non-Javadoc) * ${see_to_overridden} */</template></templates>
自己写好的模板.xml文件如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?><templates><template autoinsert="false" context="filecomment_context" deleted="false" description="Comment for created Java files" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.filecomment" name="filecomment"/><template autoinsert="false" context="constructorcomment_context" deleted="false" description="Comment for created constructors" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.constructorcomment" name="constructorcomment"> /** * Description: * @author hp DateTime ${date} ${time} * ${tags} */ </template><template autoinsert="false" context="methodcomment_context" deleted="false" description="Comment for non-overriding methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.methodcomment" name="methodcomment"> /** * Description: * @author hp DateTime ${date} ${time} * ${tags} */</template><template autoinsert="false" context="fieldcomment_context" deleted="false" description="Comment for fields" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.fieldcomment" name="fieldcomment"> /** * Description: * @author hp DateTime ${date} * */</template><template autoinsert="false" context="typecomment_context" deleted="false" description="Comment for created types" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.typecomment" name="typecomment"> /** * Class Name: ${file_name} * Description: * @author hp DateTime ${date} ${time} * @company bvit * @email hu.peng@bvit.com.cn * @version 1.0 * ${tags} */</template><template autoinsert="false" context="gettercomment_context" deleted="false" description="Comment for getter method" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.gettercomment" name="gettercomment"> /** * @return get ${bare_field_name} */</template><template autoinsert="false" context="overridecomment_context" deleted="false" description="Comment for overriding methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.overridecomment" name="overridecomment"> /** * Description: * @author hp DateTime ${date} ${time} * ${tags} */</template><template autoinsert="false" context="delegatecomment_context" deleted="false" description="Comment for delegate methods" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.delegatecomment" name="delegatecomment"> /** * Description: * @author hp DateTime ${date} * ${tags} * ${see_to_target} */</template><template autoinsert="false" context="settercomment_context" deleted="false" description="Comment for setter method" enabled="true" id="org.eclipse.jdt.ui.text.codetemplates.settercomment" name="settercomment"> /** * @param ${param} set ${bare_field_name} */</template></templates>
