}|code-block|syntax|javascript|4i7e2|诀窍是使用ArgumentMatchers.<Object>any()，因为有多个queryForList方法实现，我们要模拟的方法接收一个varargs参数。|offset|length|style|CODE|1ngb2^0|0|0|5|U|15|C|0^^$0|$]|1|@$2|3|4|5|6|7|8|O|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|P|9|@]|A|@]|B|$F|G]]|$2|H|4|I|6|7|8|Q|9|@$J|R|K|S|L|M]|$J|T|K|U|L|M]]|A|@]|B|$]]|$2|N|4|-4|6|7|8|V|9|@]|A|@]|B|$]]]]

This should work:

<pre><code>import org.hamcrest.CoreMatchers;
import org.junit.Assert;
import org.junit.Test;
import org.mockito.ArgumentMatchers;
import org.mockito.Mockito;
import org.springframework.jdbc.core.JdbcTemplate;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

public class DemoTest {

 @Test
 public void mockJdbcTemplate() {
 JdbcTemplate mockTemplate = Mockito.mock(JdbcTemplate.class);

 List&lt;Map&lt;String, Object&gt;&gt; mockResult = new ArrayList&lt;&gt;();

 Mockito.when(mockTemplate.queryForList(Mockito.anyString(), ArgumentMatchers.&lt;Object&gt;any())).thenReturn(mockResult);
 // Alternatively:
 // when(mockTemplate.queryForList(anyString(), Mockito.&lt;Object&gt;any())).thenReturn(mockResult);

 String query = "some query";
 Object[] params = new Object[]{1};

 List&lt;Map&lt;String, Object&gt;&gt; returnedResult = mockTemplate.queryForList(query, params);

 Assert.assertThat(returnedResult, CoreMatchers.sameInstance(mockResult));
 }

}
</code></pre>

The trick is to use <code>ArgumentMatchers.&lt;Object&gt;any()</code> as there are multiple <code>queryForList</code> method implementations and the one we want to mock receives a varargs parameter.

Following code i used with spring boot, mockito
<pre><code>/** class on which uni test is driven **/
public class Decompile {


 @Autowired
 private JdbcTemplate jdbcTemplate;

 public List&lt;Map&lt;String, Object&gt;&gt; getRunner()
 {
 try{
 return jdbcTemplate.queryForList(&quot;select * from users&quot;);
 } 
 catch (Exception e) {
 System.err.println(e);
 }
 return null;
 }

}

Unit test case starts

mvn package used as following (compatible with spring version &gt; 2)

 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;

I want to know how to mock the particular code using Mockito:

<pre><code>List&lt;Map&lt;String, Object&gt;&gt; list = jdbcTemplate.queryForList(
 sqlQuery, 
 new Object[] { inflowId }
);
</code></pre>

I tried the following code:

<pre><code>Mockito.doReturn(list)
 .when(jdbcTemplate)
 .queryForList(Mockito.anyString(), Mockito.any(Class.class));
</code></pre>

and:

<pre><code>when(
 jdbcTemplate.queryForList(Mockito.anyString(), Mockito.any(Object[].class))
).thenReturn(list);
</code></pre>

My problem is that particular method is not getting mocked in JUnit. When the method is called, it returns <code>null</code> whereas it should return the list.
