因为想在配置文件处控制程序，所以想设计这种参数是可变的，testClass_1/2/3是单例。
代码如下，请问可否生成TestClassArray 对象？
我试了下 生成失败了。或许有什么方法支持生成这种可变参数对象的吗？
js：
testOutList: {
type: 'com.TestClassArray',
args : [{refer: 'testClass_1'}, {refer: 'testClass_2'}, {refer: 'testClass_3'}]
}
java：
public class TestClassArray {
public TestClassArray(Object... args){
...
}
}
"种类1/2/3"是传入的参数Object值
log如下：

请问 我改写成args :[[{refer: 'testClass_1'}, {refer: 'testClass_2'}, {refer: 'testClass_3'}]]
也是失败了

我刚刚试了一下
// test.json
{
abc : {type:"java.lang.Object"},
def : {type:"java.lang.Object"},
ghi : {type:"java.lang.Object"},
testClassArray: {
type: 'net.wendal.nutzbook.TestClassArray',
args : [{refer: 'abc'}, {refer: 'def'}, {refer: 'ghi'}]
}
}
TestClassArray类与你的一样
package net.wendal.nutzbook;
public class TestClassArray {
public TestClassArray(Object... args) {}
}
testcase方法
@Test
public void test_ioc_var_args() throws IOException {
ioc.get(TestClassArray.class);
}
是可以pass的哦.
要不你把testClass_1等定义也贴出来吧
