单元测试如下：
public class JsonDeserializeTest {
@Test
public void test() {
String data = "{\"field1\": null, \"field2\": null, \"field3\": \"1\", \"field4\": \"null\"}";
Model model;
try {
model = JSON.parseObject(data, Model.class);
} catch (Exception e) {
throw new IllegalStateException("parse " + data + " to object failed.", e);
}
Assert.assertEquals(model.field1, 0);
Assert.assertEquals(model.field2, 0F);
Assert.assertEquals(model.field3, "1");
Assert.assertNull(model.field4);
Assert.assertEquals(model.field5, 10000);
}
public static class Model {
public final int field1;
public final float field2;
public final String field3;
public final List<String> field4;
public int field5 = 0;
public Model(int field1, float field2, String field3, List<String> field4) {
this.field1 = field1;
this.field2 = field2;
this.field3 = field3;
this.field4 = field4;
this.field5 = 10000;
}
}
}报错如下：
java.lang.AssertionError: expected [null] but found [[null]]
Expected :null
Actual :[null]
