HomeDatabaseMysql TutorialJava操作MySQL的中文处理方法_MySQL

  1、建立一个类,包括一个格式将中文转换为ISO8859-1编码的方法:  

publicclass Format2Chinese {
  public Format2Chinese() {
  }
  public String format2IS08859(String str) {
  try {
  if (str == null    str.trim().equals(""))
  str = "";
  else
  str = new String(str.getBytes("ISO8859-1"));
  } catch (Exception e) {
  e.printStackTrace();
  }
  return str;
  }
  }

  2、你的bean里面这时就要加一些东西了,如下面这个简单的bean:  

publicclass Leavemsg
  {
  public Leavemsg() {
  }
  //这个要加的,因为写入的时候我们不格式,写出的时候格式化
  public Leavemsg(boolean format) {
  this.format = format;
  }
  private String msg;
  booleanformat = false; //用于确定是否将字符格式转换
  Format2Chinese function = new Format2Chinese();
  publicvoid setMsg(String msg) {
  if (format) {
  this.msg = function.format2IS08859(msg);
  } else
  this.msg = msg;
  }
  public String getMsg() {
  return msg;
  }
  }

  3、在用bean装数据的时候,这样声明:

  Leavemsg msg=new Leavemsg(true); 然后其它的操作都是一样的,就OK了。

  这时页面显示中文的时候就不会出问题了,在JSP页面里这可以这样,用该类做包装得到的内容。

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
