Joget DX 8 Stable Released
The stable release for Joget DX 8 is now available, with a focus on UX and Governance.
本文主要解释如何 使用Bean Shell 表单绑定器 从表单表格中 加载/读取 数据 . 如果您需要从多个表中加载/存储表单数据,这可能非常方便。
加载绑定器 -> Bean Shell表单绑定器
import org.joget.apps.form.model.*; import org.joget.apps.form.service.*; import java.sql.*; import org.apache.commons.collections.SequencedHashMap; import java.util.*; public FormRowSet test() { FormRowSet f = new FormRowSet(); f.setMultiRow(true); Class.forName("com.mysql.jdbc.Driver").newInstance(); con = DriverManager.getConnection("jdbc:mysql://localhost:3307/jwdb?characterEncoding=UTF-8", "database username", "database password"); if(!con.isClosed()){ String recordId = "#requestParam.id#"; // Get the url parameter String sql = "SELECT * FROM test_table WHERE id=?"; // Here you can query from one or multiple tables using JOIN etc PreparedStatement stmt = con.prepareStatement(sql); stmt.setString(1, recordId); ResultSet rs = stmt.executeQuery(); while (rs.next()) { FormRow r1 = new FormRow(); r1.put("gridColumn1", rs.getString(1)); r1.put("gridColumn1", rs.getString(2)); r1.put("gridColumn1", rs.getString(3)); f.add(r1); } } return f; } return test();
存储绑定器 -> Bean Shell 表单绑定器
import org.joget.apps.form.model.*; import org.joget.apps.form.lib.*; import org.joget.apps.form.service.*; import java.sql.*; import org.apache.commons.collections.SequencedHashMap; import java.util.*; import org.joget.commons.util.UuidGenerator; public FormRowSet getGridRows() { return rows ; // this will return the grid rows } public saveGridRows(FormRowSet rows) { Class.forName("com.mysql.jdbc.Driver").newInstance(); con = DriverManager.getConnection("jdbc:mysql://localhost:3307/jwdb?characterEncoding=UTF-8", "database username", "database password"); if(!con.isClosed()){ String recordId = "#requestParam.id#"; // If you need to query data from different table(s) and process it before saving it to database, // you can do it here UuidGenerator uuid = UuidGenerator.getInstance(); Iterator i= rows.iterator(); // Iterating grid rows while (i.hasNext()) { FormRow row = (FormRow) i.next(); String gridColumn1 = row.get("gridColumn1"); // reading grid column value String gridColumn2 = row.get("gridColumn2"); String gridColumn3 = row.get("gridColumn3"); String pId = uuid.getUuid(); // generating Primary Key String insertSql = "INSERT INTO table(id,col1,col2,col3) VALUES(?,?,?,?)"; PreparedStatement stmtInsert = con.prepareStatement(insertSql); stmtInsert.setString(1, pId); stmtInsert.setString(2, gridColumn1); stmtInsert.setString(3, gridColumn2); stmtInsert.setString(4, gridColumn3); stmtInsert.executeUpdate(); } } else { System.out.println("Connection Problem"); } con.close(); } FormRowSet rows = getGridRows(); // getting the grid rows saveGridRows(rows); // processing & storing the grid rows
表格设计
正确的表格设计应如下所示:
部分load binder beanshell脚本:
FormRowSet f = new FormRowSet(); f.setMultiRow(true); FormRow r1 = new FormRow(); r1.put("gridColumn1", your_value); r1.put("gridColumn2", your_value); r1.put("gridColumn3", your_value); f.add(r1);
