mybatis源码

1. 若要查询本次查询的sql,怎么弄？

 

--》往下走：该prepareStatement中就可以看到sql

 

 

3.RoutingStatementHandler  路由Statement，该方法在prepare之前执行

  

public RoutingStatementHandler(Executor executor, MappedStatement ms, Object parameter, RowBounds rowBounds, ResultHandler resultHandler, BoundSql boundSql) {
        switch(ms.getStatementType()) {
        case STATEMENT:
            this.delegate = new SimpleStatementHandler(executor, ms, parameter, rowBounds, resultHandler, boundSql);
            break;
        case PREPARED:
            this.delegate = new PreparedStatementHandler(executor, ms, parameter, rowBounds, resultHandler, boundSql);
            break;
        case CALLABLE:
            this.delegate = new CallableStatementHandler(executor, ms, parameter, rowBounds, resultHandler, boundSql);
            break;
        default:
            throw new ExecutorException("Unknown statement type: " + ms.getStatementType());
        }

    }
