weka鏈接sqlserver或MySQL步驟相同，只不過驅動和轉換文件不一樣。html

一、首先，下載weka，解壓weka.jar；java

二、找到weka\experiment 文件夾下的DatabaseUtils.props.mssqlserver（鏈接sqlserver）或DatabaseUtils.props.mysql（鏈接mysql）進行修改：mysql

（這裏的weka目錄是指weka.jar文件，使用壓縮軟件打開顯示）sql

sqlserver驅動加載：
# JDBC driver (comma-separated list)
jdbcDriver=com.microsoft.jdbc.sqlserver.SQLServerDriver
　　數據庫鏈接：數據庫

　　若是在本機上能夠將server_name改成127.0.0.1或者localhost
# database URL
jdbcURL=jdbc:sqlserver://server_name:數據庫名服務器

mysql驅動加載：
# JDBC driver (comma-separated list)
jdbcDriver=org.gjt.mm.mysql.Driver
　　數據庫鏈接：app

# database URL
jdbcURL=jdbc:mysql://server_name:3306/數據庫名sqlserver

　　數據類型的轉換：this

　　因爲weka僅支持名詞型（nominal）、數值型（numeric）、字符串、日期（date）。因此咱們要將如今數據庫中的數據類型對應到這四種類型上來。url

　　如下數據類型對應的句子前面的註釋符合去掉。因爲SQL Server2000有其餘的數據類型Weka尚不能識別，因此咱們在下面再添加上
smallint=3
datetime=8等等

string,getString()= 0; -->nominal
boolean,getBoolean() = 1; -->nominal
double,getDouble() = 2; -->numeric
byte,getByte() = 3; -->numeric
short,getByte()= 4; -->numeric
int,getInteger() = 5; -->numeric
long,getLong() = 6; -->numeric
gloat,getFloat() = 7; -->numeric
date,getDate() = 8; -->date
varchar=0 //主要是這下面四行，找對位置加上
float=2
tinyint=3
int=5
其餘說明，咱們暫時用不到，不用去管了
# other options
CREATE_DOUBLE=DOUBLE PRECISION
CREATE_STRING=VARCHAR(8000)
CREATE_INT=INT
checkUpperCaseNames=false
checkLowerCaseNames=false
checkForTable=true

三、複製到主目錄中並重命名爲DatabaseUtils.props；

四、主目錄中新建文件夾名爲lib；下載驅動到lib中，如：sqljdbc或mysql-connector-Java-5.1.39-bin

五、修改RunWeka.ini，在文件的最後修改成

cp=%CLASSPATH%;F:\Weka-3-8\lib\mysql-connector-java-5.1.39-bin.jar（驅動的位置）

保存；

六、配置環境，

「個人電腦」屬性，設置環境變量

（1）新建變量WEKA_HOME，值爲weka的安裝目錄，如（F:\Weka-3-8）

（2）在CLASSPATH變量中添加「；%WEKA_HOME%\lib\mysql-connector-java-5.0.8-bin.jar」

（注意驅動的版本號與電腦中版本號一致）

七、運行weka，進入explorer——>open DB

在URL框中輸入：jdbcURL=jdbc:mysql://localhost:3306/數據庫名（localhost是服務器名稱，注：確保數據庫存在）點擊user：輸入用戶名和密碼後，點擊connect；若是下面的info框中，顯示connecting to :jdbc:mysql://localhost:3306/數據庫名=true,則鏈接成功；不然失敗。

若失敗，可在評論中說明，我會盡可能解答。
