导读:我想知道jdbi sql api处理赏罚sql查询毕竟是什么用于调试目标. 我的接口类如下 public inteface myinteface{ @SqlQuery("select :c1 from tablename where cond = :cd") String returnMeValue(@Bind("c1") String c1,@Bind("cd") Integer cd);} 然后在另一个类中
我想知道jdbi sql api处理赏罚sql查询毕竟是什么用于调试目标.
public inteface myinteface{ @SqlQuery("select :c1 from tablename where cond = :cd") String returnMeValue(@Bind("c1") String c1,@Bind("cd") Integer cd); } 然后在另一个类中挪用String result = myinterfaceclassobject.returnMeValue(“Name”,1); 我没有获得预期的谜底以是我想看看现实上是什么进入sql查询.那么有什么要领可以得到最终处理赏罚的查询吗? 办理要领您可以通过编写SqlCustomizer来记录sql.import org.skife.jdbi.v2.StatementContext; import org.skife.jdbi.v2.sqlobject.SqlStatementCustomizer; import org.skife.jdbi.v2.sqlobject.SqlStatementCustomizerFactory; import org.skife.jdbi.v2.sqlobject.SqlStatementCustomizingAnnotation; import org.skife.jdbi.v2.tweak.StatementCustomizer; import java.lang.annotation.*; import java.lang.reflect.Method; import java.sql.PreparedStatement; import java.sql.SQLException; @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) @SqlStatementCustomizingAnnotation(LogSqlFactory.Factory.class) public @interface LogSqlFactory { static class Factory implements SqlStatementCustomizerFactory { @Override public SqlStatementCustomizer createForMethod(Annotation annotation,Class sqlObjectType,Method method) { return null; } @Override public SqlStatementCustomizer createForType(Annotation annotation,Class sqlObjectType) { return q -> q.addStatementCustomizer(new StatementCustomizer() { @Override public void beforeExecution(PreparedStatement stmt,StatementContext ctx) throws SQLException { System.out.println(stmt.toString()); } @Override public void afterExecution(PreparedStatement stmt,StatementContext ctx) throws SQLException { } @Override public void cleanup(StatementContext ctx) throws SQLException { } }); } @Override public SqlStatementCustomizer createForParameter(Annotation annotation,Method method,Object arg) { return null; } } } 只需包括此注释并在SqlObject中行使它.在你的环境下行使这样的注释, @LogSqlFactory public inteface myinteface{ @SqlQuery("select :c1 from tablename where cond = :cd") String returnMeValue(@Bind("c1") String c1,@Bind("cd") Integer cd); } 假如行使自界说记录器举办日记记录,则行使beforeExecution要领.
