{ "F_NUMBER": "", "VER": "", "BOM_DATA": [{ "COMPS": "", "burnDesc": "", }], "BOM_STATUS": "", "itemLines": [{ "item_number": "3.7.01.10.00212", "lifecyclephase": "Development", "rev_number": "03" }] }, "ECN_DATA": { "ecnBefore": "", "ecnAfter": "", "ecnSwitch": "", } "zxbz": "" }解析3分别存入数据表

对于给出的 JSON 数据，可以将其解析为三个数据表：

1. BOM_DATA 表：该表存储 BOM_DATA 字段中的数据。其中每个元素的 COMPS 和 burnDesc 存储在同一行中。可以使用 BOM_DATA 表的 ID 作为外键与 itemLines 表建立关联。

| ID | COMPS | burnDesc |
|----|-------|----------|
| 1 | ... | ... |
| 2 | ... | ... |
| ...| ... | ... |

2. itemLines 表：该表存储 itemLines 字段中的数据。

| ID | item_number | lifecyclephase | rev_number |
|----|-----------------|----------------|------------|
| 1 | 3.7.01.10.00212 | Development | 03 |
| ...| ... | ... | ... |

3. ECN_DATA 表：该表存储 ECN_DATA 字段中的数据。

| ID | ecnBefore | ecnAfter | ecnSwitch |
|----|-----------|----------|-----------|
| 1 | ... | ... | ... |

{ "F_NUMBER": "", "VER": "", "BOM_DATA": [{ "COMPS": "", "burnDesc": "", }], "BOM_STATUS": "", "itemLines": [{ "item_number": "3.7.01.10.00212", "lifecyclephase": "Development", "rev_number": "03" }] }, "ECN_DATA": { "ecnBefore": "", "ecnAfter": "", "ecnSwitch": "", } "zxbz": "" }解析分别插入oracle表中java代码

假设你已经连接到了Oracle数据库，有以下两个表需要插入数据：

- BOM_DATA表：字段有F_NUMBER、VER、COMPS、burnDesc、BOM_STATUS；
- ITEM_LINES表：字段有ITEM_NUMBER、LIFECYCLEPHASE、REV_NUMBER；
- ECN_DATA表：字段有ECN_BEFORE、ECN_AFTER、ECN_SWITCH；
- ZX_BZ表：字段有ZX_BZ_DATA。

那么可以使用以下Java代码将JSON字符串解析后插入各自的表中：

import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.List;
import java.util.Map;

        PreparedStatement pstmt = conn.prepareStatement(sql);
        for (int i = 0; i < bomDataArr.size(); i++) {

            pstmt.addBatch();
        }
        pstmt.executeBatch();
        pstmt.close();

        pstmt.setString(2, ecnDataObj.getString("ecnAfter"));

        pstmt.setString(1, zxbzData);
        pstmt.executeUpdate();
        pstmt.close();
    }
    
    // 获取数据库连接
    private Connection getConnection() {
        // TODO：获取数据库连接的代码
    }
}

需要注意的是，这里使用了阿里巴巴的fastjson库来解析JSON字符串。如果你没有使用过该库，需要先将其添加到项目的依赖中。另外，这里没有考虑到异常处理等情况，需要你自行添加。

for i in range(len(comps)):

This is a Python code snippet that iterates through a range of numbers based on the length of a list called "comps".

The "range" function generates a sequence of numbers starting from 0 up to (but not including) the length of "comps". The "len" function returns the number of elements in "comps".

The variable "i" is used to represent each number in the sequence, and the loop executes the indented code block once for each number in the sequence.
