GB32960 Body Parser — Per-Block Exception Isolation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Gb32960BodyParser 主循环对单信息块的解析异常实现单块隔离:一块解析失败不再整帧放弃,改为把失败块兜成 InfoBlock.Raw 并继续解析后续信息块。

Architecture: 在主循环每次 parser.parse(body) 外面套 try/catch仅捕获 DecodeException / BufferUnderflowException / IndexOutOfBoundsException,放行 RuntimeException 以免掩盖 parser bug。失败时

  • fixedLen ≥ 0 且剩余字节 ≥ fixedLen → 回滚 reader → 按 fixedLen 截取 Raw → position 前进 fixedLen → continue 循环
  • 否则(变长 parser 或剩余不足)→ 剩余字节全部兜成 Raw → break 循环(变长块无法安全找下一块边界)

通过 Gb32960Properties.Parse.lenientBlockFailure(默认 true控制开关可以回退到严格模式。不改 InfoBlock.Raw record 结构(避免 downstream 兼容风险——Gb32960EventMapperfindBlock(Class) 类型查找,新增 Raw 不影响其行为)。

Tech Stack: Java 25, JUnit 5, AssertJ, Spring Boot ConfigurationProperties, Maven。仅改动 protocol-gb32960 模块。


File Structure

  • Modify protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960Properties.java — 新增 Parse 内嵌类 + parse 字段/getter/setter
  • Modify protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/codec/Gb32960BodyParser.java — 主循环 try/catch + recovery 逻辑 + lenientBlockFailure 字段
  • Modify protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960AutoConfiguration.java — 把配置穿给 BodyParser
  • Create protocol-gb32960/src/test/java/com/lingniu/ingest/protocol/gb32960/codec/Gb32960BodyParserIsolationTest.java — 3 个隔离场景 + 1 个严格模式回退场景
  • Modify bootstrap-all/src/main/resources/application.yml — 添加 parse: 注释段示例
  • Modify CHANGELOG.md — 追加本次变更条目

Task 1: 基线验证 —— 现有测试全绿

Files:

  • Step 1.1: 跑 protocol-gb32960 模块测试

Run: mvn -pl protocol-gb32960 test -q Expected: BUILD SUCCESS所有现有测试通过Gb32960DecoderGoldenTestGb32960FullBlocksTestGb32960DecoderTestGuangdongFcEndToEndTest、parser/* 各 Block Parser 单测、profile/* 选择器单测)。

如果基线红了,先停下来修复基线再进入 Task 2。


Task 2: 添加 Parse 配置子节点

Files:

  • Modify: protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960Properties.java

  • Step 2.1: 在 Gb32960Properties 类体中(在 Auth 字段后、Tls 字段前)新增 parse 字段

位置参考:现在 L24 private Auth auth = new Auth(); 下面一行,在 L27 private Tls tls = new Tls(); 之前插入:

    /**
     * 报文解析行为配置。
     *
     * <p>默认 {@code lenientBlockFailure=true}:单个信息块解析异常时兜成
     * {@link com.lingniu.ingest.protocol.gb32960.model.InfoBlock.Raw} 继续解析,
     * 不再整帧放弃。关闭后恢复旧行为(任意异常直接抛 {@code DecodeException}
     * 放弃整帧),仅在灰度回滚时使用。
     */
    private Parse parse = new Parse();
  • Step 2.2: 在类底部(Tls 静态类之后、VendorExtension 静态类之前)添加 Parse 静态内嵌类
    /**
     * 报文解析容错策略。
     */
    public static class Parse {
        /**
         * 单块解析异常时是否兜底为 {@link com.lingniu.ingest.protocol.gb32960.model.InfoBlock.Raw}
         * 继续解析。默认开启。
         *
         * <ul>
         *   <li>{@code true}默认parser 抛 DecodeException / BufferUnderflowException /
         *       IndexOutOfBoundsException 时,固定长度块按 fixedLen 截取 Raw 后 continue
         *       变长块或剩余字节不足时,剩余全部兜成 Raw 后 break 循环。
         *   <li>{@code false}:保留旧行为,任意异常直接抛出 DecodeException 放弃整帧。
         * </ul>
         */
        private boolean lenientBlockFailure = true;

        public boolean isLenientBlockFailure() { return lenientBlockFailure; }
        public void setLenientBlockFailure(boolean lenientBlockFailure) {
            this.lenientBlockFailure = lenientBlockFailure;
        }
    }
  • Step 2.3: 在属性 getter/setter 区域(现有 getTls 之后)补充 getParse / setParse
    public Parse getParse() { return parse; }
    public void setParse(Parse parse) { this.parse = parse; }
  • Step 2.4: 编译验证

Run: mvn -pl protocol-gb32960 compile -q Expected: BUILD SUCCESS。

  • Step 2.5: 提交
git add protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960Properties.java
git commit -m "$(cat <<'EOF'
config(gb32960): add parse.lenientBlockFailure toggle

新增 lingniu.ingest.gb32960.parse.lenientBlockFailure 配置开关(默认 true
为 Gb32960BodyParser 的单块异常隔离行为做回退开关。实现在后续 commit。

  • Step 4.4: 运行全模块测试检查回归

Run: mvn -pl protocol-gb32960 test -q Expected: BUILD SUCCESS所有原有测试含 Golden、FullBlocks、GuangdongFcEndToEnd依旧通过。

如果有原有测试红了:停下来诊断。最可能的原因是某个现有测试之前靠"抛异常"行为验证错误帧的,需要手动判断这是测试问题还是实现问题。

  • Step 4.5: 提交
git add protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/codec/Gb32960BodyParser.java \
        protocol-gb32960/src/test/java/com/lingniu/ingest/protocol/gb32960/codec/Gb32960BodyParserIsolationTest.java
git commit -m "$(cat <<'EOF'
feat(gb32960): isolate per-block parse failures in body parser

主循环改造:单信息块 parser 抛 DecodeException / BufferUnderflowException /
IndexOutOfBoundsException 时不再放弃整帧。

- 固定长度块fixedLen≥0回滚 reader按 fixedLen 截取字节兜成 InfoBlock.Raw
  position 前进 fixedLencontinue 循环继续解析后续块
- 变长块fixedLen=-1或剩余不足 fixedLen剩余字节全部兜成 Raw 后 break
- parser 契约违反consumed != declared fixedLen仍抛异常以暴露 parser bug
- 通过 lingniu.ingest.gb32960.parse.lenientBlockFailure=false 可回退严格模式
- 新增 Gb32960BodyParserIsolationTest 覆盖 3 种失败场景 + 1 严格模式

不改 InfoBlock.Raw record 结构;下游 Gb32960EventMapper 按 findBlock(Class) 类型
查找,新增 Raw 不影响其行为。

Task 5: 把配置注入 BodyParserAutoConfiguration 连线)

Files:

  • Modify: protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960AutoConfiguration.java

  • Step 5.1: 定位 Gb32960BodyParser bean 定义

先查看:grep -n "Gb32960BodyParser" protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960AutoConfiguration.java

根据返回的行号,在构造 Gb32960BodyParser 的 @Bean 方法里,构造完成后立即调用:

        Gb32960BodyParser parser = new Gb32960BodyParser(profileRegistry, selector);
        parser.setLenientBlockFailure(properties.getParse().isLenientBlockFailure());
        return parser;

(如果目前的构造返回一行表达式,改成先赋给 local 变量再设 flag 再 return。

  • Step 5.2: 编译并运行全模块测试

Run: mvn -pl protocol-gb32960 test -q Expected: BUILD SUCCESS。

  • Step 5.3: 提交
git add protocol-gb32960/src/main/java/com/lingniu/ingest/protocol/gb32960/config/Gb32960AutoConfiguration.java
git commit -m "$(cat <<'EOF'
config(gb32960): wire parse.lenientBlockFailure into BodyParser bean

Gb32960AutoConfiguration 在创建 Gb32960BodyParser bean 后,将
Gb32960Properties.Parse.lenientBlockFailure 通过 setter 注入,让运行期配置生效。

Task 6: bootstrap-all 配置文档化

Files:

  • Modify: bootstrap-all/src/main/resources/application.yml

  • Step 6.1: 在 lingniu.ingest.gb32960 节点的 vendor-extensions 段之后、jt808 之前,插入 parse 配置示例

参考位置:现有 application.yml L57 末尾(vendor-extensions list 结束)。在 L58 jt808: 之前加入:

      # 报文解析容错。默认启用单块异常隔离:某个信息块解析失败时兜成 Raw 后继续,
      # 不再整帧丢弃。仅在需要严格失败语义(灰度回滚或抓虫)时设为 false。
      parse:
        lenient-block-failure: true
  • Step 6.2: 启动一次 bootstrap-all 的 dry-run 编译

Run: mvn -pl bootstrap-all compile -q Expected: BUILD SUCCESS只是配置段注释变化不会影响编译

  • Step 6.3: 提交
git add bootstrap-all/src/main/resources/application.yml
git commit -m "$(cat <<'EOF'
config(gb32960): document parse.lenient-block-failure in application.yml

Task 7: 全仓库回归测试

Files: 无(只是验证)

  • Step 7.1: 跑完整项目测试

Run: mvn test -q Expected: BUILD SUCCESS。重点关注

  • protocol-gb32960 模块全绿Golden、FullBlocks、Isolation、GuangdongFcEndToEnd、Decoder、Mapper、所有 parser 单测、profile
  • 其它模块(ingest-coresink-mq 等)不受影响(无改动应自动通过)

若有红,停下来诊断。


Task 8: 更新 CHANGELOG

Files:

  • Modify: CHANGELOG.md

  • Step 8.1: 在 CHANGELOG.md 文件顶部(在 ## [0.1.0] — 2026-04-15 标题之前)新增一个 ## [Unreleased] 段落;如已存在则追加

新增段落内容(如已存在 Unreleased 段则在其 ### Added / ### Changed 内部追加):

## [Unreleased]

### Changed —— GB/T 32960 Body Parser 单块异常隔离
- `Gb32960BodyParser` 主循环对单信息块的 parser 异常不再放弃整帧:
  - 固定长度块(`fixedLength ≥ 0`):回滚 reader → 按 fixedLen 截取字节兜成
    `InfoBlock.Raw` → 继续解析后续块;
  - 变长块或剩余字节不足:剩余字节全部兜成 `Raw` 后终止循环;
  - `parser` 契约违反(声明 fixedLen=X 但实际读了 Y仍抛 `DecodeException`
    以暴露 parser bug不被静默吞掉
  - 只捕获 `DecodeException` / `BufferUnderflowException` / `IndexOutOfBoundsException`
    `RuntimeException` 继续向上抛,保留 bug 可见性。
- 新增配置 `lingniu.ingest.gb32960.parse.lenient-block-failure`(默认 `true`
  回退严格模式用 `false`- `InfoBlock.Raw` record 结构**未变**,下游 `Gb32960EventMapper``findBlock(Class)`
  类型匹配,新增 Raw 不影响业务事件映射。
- 覆盖测试:`Gb32960BodyParserIsolationTest` —— 3 种隔离场景 + 严格模式回退。
  • Step 8.2: 提交
git add CHANGELOG.md
