javadoc命令用于生成类似标准Java API的注释文档。

1. javadoc可以识别的注释

  @author
  @version
  @since
  @param
  @throws

  package com.langtao.base;

  /**
   * @author langtao
   * @version 1.0
   * @since 1.8
   */

  public class Doc {
      String name = "";

      /**
       * @author langtao
       * @return
       * @throws Exception
       */
      public String test() throws Exception {
          return name;
      }

  }

2. 使用命令行生成java

  javadoc Doc.java
