ibatis example Class 使用

example Class 使用(可以使用逻辑运算的结合律简化where条件)

代码： 
TestTableExample example = new TestTableExample(); 
example.createCriteria().andField1EqualTo(5);

产生条件:

where field1 = 5

代码:

TestTableExample example = new TestTableExample();

example.createCriteria() 
.andField1EqualTo(5) 
.andField2IsNull();

example.or(example.createCriteria() 
.andField3NotEqualTo(9) 
.andField4IsNotNull());

List<Integer> field5Values = new ArrayList<Integer>(); 
field5Values.add(8); 
field5Values.add(11); 
field5Values.add(14); 
field5Values.add(22);

example.or(example.createCriteria() 
.andField5In(field5Values));

example.or(example.createCriteria() 
.andField6Between(3, 7));

产生条件:

where (field1 = 5 and field2 is null) 
or (field3 <> 9 and field4 is not null) 
or (field5 in (8, 11, 14, 22)) 
or (field6 between 3 and 7)
