Any method that is not declaredvoidmust contain areturnstatement with a corresponding return value, like this: return returnValue; The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean. The...
add(m); } } return result; } 十、TestNG侦听器 有几个接口可让您修改TestNG的行为。这些接口广泛地称为“ TestNG侦听器”。以下是一些听众: IAnnotationTransformer(doc,javadoc) IAnnotationTransformer2(doc,javadoc) IHookable(doc,javadoc) IInvokedMethodListener(doc,javadoc) IMethodInterceptor(doc,...

在切面的前置方法「beforeMethod」统一拦截查询参数，配合自定义的注解，加密指定的字段。然后在切面的后置方法「afterReturn」拦截返回值，配合自定义注解，解密指定的字段。但是 Spring AOP 方案也并不通用，如果其他的应用也有相同的需求，同样的代码，又需要重复实现，还是很费时费力。最终我们参考一个 github 开源...
MATLAB only converts object data return values if the method signature specifiesjava.lang.Object. If the signature specifies any other object type, then MATLAB does not convert the value. For example, MATLAB does convert the return value for this method signature: ...

2 单独几个参数 单独几个参数的时候,在接口方法处需要加注解@Param("参数名"),参数名以便在sql中按顺序引用。一个参数时候,可以省略(最好加上) 返回影响行数int 增删改语句默认返回影响的行数int,xml中可以不写返回值类型。 多条记录返回List/嵌套的Map集合 注意: 1:多参数入参,所以不用在xml中写...
