一,为减小 build.xml 文件的大小,使用XML实体
把属性的设置都放一个XML文件中
props.xml 文件
property name="build.dir" value="build" />
然后在 build.xml 文件中加入如下
DOCTYPE project []>
二,将多个目录的源文件编译到一个地方
javac destdir="build/classes">
src path="src1"/>
src path="src2"/>
javac>
三,保存构建时的信息
project default="init">
target name="init">target>
property environment="env" />
property name="env.COMPUTERNAME" value="${env.HOSTNAME}" />
propertyfile comment="Build Information" file="./buildinfo.properties">
entry key="build.host" value="${env.COMPUTERNAME}" />
entry key="build.user.name" value="${user.name}" />
entry key="build.os.name" value="${os.name}" />
propertyfile>
project>
四,去除属性文件的注释
属性文件:
# 这里是注释,会给过滤掉
build.dir = build
build文件:
copy file="props.properties" todir="sample">
filterchain>
striplinecomments>
comment value="#" />
striplinecomments>
filterchain>
copy>
五,两个花俏的功能
1.声音提示
project name="Sound" default="all">
property file="build.properties" />
target name="init">
sound>
success source="${sound.dir}/success.wav" duration="500" />
fail source="${sound.dir}/fail.wav" loops="2" />
sound>
target>
target name="fail" depends="init">
fail />
target>
target name="success" depends="init" />
target name="all" depends="success" />
project>
2.进度条提示
project name="splash" default="init">
target name="init">
splash imageurl="http://java.chinaitlab.com/UploadFiles_8734/200610/20061021103415601.gif" showduration="5000" />
sleep seconds="1" />
sleep seconds="1" />
sleep seconds="1" />
sleep seconds="1" />
sleep seconds="1" />
sleep seconds="1" />

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.
