[咨询] 字段映射问题

[hany5725]

Description

我使用字段映射功能，重写了setColumn和getKey方法，在初始化时正常输入内容，但是当我调用查询时，ColumnUtil.VERSIONED_KEY_COLUMN_MAP为空了

代码内容
public class TunnelSqlConfig extends APIJSONSQLConfig {

/**
 * 默认构造函数
 */
public TunnelSqlConfig() {
    super();
}

/**
 * 带参数构造函数
 *
 * @param method 请求方法
 * @param table  表名
 */
public TunnelSqlConfig(RequestMethod method, String table) {
    super(method, table);
}

static {
    // 设置逻辑删除字段
    KEY_DELETED_KEY = "del_flag";
    KEY_DELETED_VALUE = "1";
    KEY_NOT_DELETED_VALUE = "0";
    // 设置默认数据库类型和模式
    DEFAULT_DATABASE = DATABASE_MYSQL;
    DEFAULT_SCHEMA = SystemProperties.Database.getDefaultSchema();

    // 配置SQL配置回调
    SIMPLE_CALLBACK = new SimpleCallback<String>() {

        /**
         * 获取SQL配置实例
         *
         * @param method     请求方法
         * @param database   数据库名
         * @param schema     模式名
         * @param datasource 数据源名
         * @param table      表名
         * @return SQL配置实例
         */
        @Override
        public AbstractSQLConfig<String> getSQLConfig(RequestMethod method, String database, String schema, String datasource, String table) {
            return new TunnelSqlConfig(method, table);
        }

        /**

         */
        @Override
        public String getUserIdKey(String database, String schema, String datasource, String table) {
            return USER_.equals(table) || PRIVACY_.equals(table) ? ID : USER_ID;
        }
    };

    tableKeyColumnMap.put("BallastlessLedger", ballastlessLedgerColumnMap);

    ColumnUtil.VERSIONED_KEY_COLUMN_MAP.put(1, tableKeyColumnMap);

    // 初始化列工具
    ColumnUtil.init();

    // 调试：检查初始化结果
    System.out.println("映射配置初始化完成");
    System.out.println("表映射: " + ColumnUtil.VERSIONED_KEY_COLUMN_MAP.get(1).keySet());

}

@Override
public AbstractSQLConfig<String> setColumn(List<String> column) {
    System.out.println(ColumnUtil.VERSIONED_KEY_COLUMN_MAP);
    List<String> list = ColumnUtil.compatInputColumn(column, getTable(), getMethod(), 1, false);

@hany5725 应该是自定义的 TunnelSqlConfig 没注册导致字段配置没用上
#363
#812

[hany5725]

@TommyLemon 有进行正常的初始化配置

启动类主方法：

这是我的APIJSONConfig配置：

public class ApiJsonConfig {

/**
 * 初始化APIJSON配置
 */
public static void initApiJsonConfig() {
    // 配置APIJSON创建器
    configureApiJsonCreator();

    // 配置Spring实例获取器
    configureInstanceGetter();

    // 配置JSON回调处理器
    configureJsonCallback();

    log.info("APIJSON配置初始化完成");
}

/**
 * 配置APIJSON创建器
 */
private static void configureApiJsonCreator() {
    APIJSONApplication.DEFAULT_APIJSON_CREATOR = new APIJSONCreator<String>() {

        @Override
        public Parser<String> createParser() {
            return new TunnelParser();
        }

        @Override
        public FunctionParser<Long> createFunctionParser() {
            return new TunnelFunctionParser();
        }

        @Override
        public Verifier<String> createVerifier() {
            return new TunnelVerifier();
        }

        @Override
        public SQLConfig<String> createSQLConfig() {
            return new TunnelSqlConfig();
        }

        @Override
        public SQLExecutor<String> createSQLExecutor() {
            return new TunnelSqlExecutor();
        }
    };
}

断点调试 setColumn 和 getKey，发下截屏，包含对应变量的值

[hany5725]

这是初始化的断点信息：

查询条件：
{
"BallastlessLedger[]": {
"count": 20,
"page": 0,
"BallastlessLedger": {
"delFlag": "0",
"@order": "createTime-"
},
"query": 2
},
"total@": "/BallastlessLedger[]/total"
}

查询的调试信息：

错误日志：

表结构：

[TommyLemon]

断点 getClosestValue ，看看为啥对 keyColumnMap 返回了 null

[hany5725]

init方法时正常的，实际调用时候

项目初始化启动时

在查询时 这三个静态变量都为空了
