针对oracle数据库：
/**
* Description: 处理转义字符%和_，针对ORACLE数据库
*
* @param str
* @return
*/
public static String escapeStr(String str) {
String temp = "";
for (int i = 0; i < str.length(); i++) {
if (str.charAt(i) == '%' || str.charAt(i) == '_') {
temp += "\\" + str.charAt(i);
} else {
temp += str.charAt(i);
}
}
return temp;
}
并调用工具类处理
String areaname = request.getParameter("Areaname");
if (areaname != null) {
if ("".equals(areaname)) {
areaname = null;
} else {
areaname = StringUtils.escapeStr(areaname);
}
}
<if test="param.areaname!=null"> and areaname like '%'||#{param.areaname}||'%' escape '\'</if>
select * from t_user where name like ' %${value}% '
select * from t_user where name like '%'||${value}||'%'
select * from t_user where name like #{do_it_in_java}
