昨日一同事喊我去他的机子上救火,告诉我折腾了半天,还是存在中文乱码问题。15分钟后找到了问题的原因。 现象: url = jdbc:mysql://127.0.0.1/test?useUnicode=true amp; characterEncoding=UTF-8,这段代码出现在配置文件(database.properties)中。 分析:

昨日一同事喊我去他的机子上救火,告诉我折腾了半天,还是存在中文乱码问题。15分钟后找到了问题的原因。

    现象:url = jdbc:mysql://127.0.0.1/test?useUnicode=true&characterEncoding=UTF-8,这段代码出现在配置文件(database.properties)中。
   
    分析:上述是原先写的,问题就在& xml/html转译符上,在xml/html里面需要写成转义符,但是在纯文本的模式下写成那样就不对了,将导致配置参数无效,原来问题出在一个标点符号上

      去掉amp; 写成 url = jdbc:mysql://127.0.0.1/test?useUnicode=true&characterEncoding=UTF-8,即可。

收工以前,做了五分钟的科普向同事们总结了一下,一般导致中文乱码问题7点因素:

    1.数据库使用的字符集 
    2.数据库表使用的字符集
    3.html、JSP 页面上的编码
    4.使用的JDBC  url连接是否正确
    5.web服务器端 应用服务器 和 操作系统 设置的字符集是否和你需要的匹配
    6.你的IDE开发环境(Eclipse)工程使用的字符集是否匹配
    7.检查你的工程的web.xml文件是否在使用关于字符编码的过滤器

以上几点原因都是导致产生中午乱码的因素,如果你的项目中出现了中文乱码不妨可以按照上述思路试试。

Break or return from Java 8 stream forEach? Break or return from Java 8 stream forEach? Feb 07, 2025 pm 12:09 PM

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is
