我制作了一个简单的Web服务,必须使用指定的uuid为用户更新acrive字段。
P
ublic String UpdateDB(UUID choUUIID ) throws ClassNotFoundException
{
String strDelReturn = "UPDATE_FAIL";
Class.forName("org.postgresql.Driver");
try
{
conn = DriverManager.getConnection(
"jdbc:postgresql://localhost:5432/plovdivbizloca",
"postgres", "tan");
}
catch (SQLException ex)
{
ex.printStackTrace();
}
PreparedStatement pstmt = null;
String selectQuery = "update users set active=active+1 WHERE uuid="+ choUUIID ;
try {
pstmt = conn.prepareStatement(selectQuery);
int rowss = pstmt.executeUpdate();
if (rowss != 0)
strDelReturn = "UPDATE_OK";
}
catch (Exception ex)
{
}
return strDelReturn;
}
我从postgresql数据库中获取参数choUUIID(该字段是uuid类型) 但是,我测试它
http://localhost:9091/Hashing_Passwords/services/Hashing_Password/UpdateDB?choUUIID=d99620ae-20a3-46f7-adb1-1afd0e8f3b27
