title: Asserting array of arrays with JSONPath and spring mvc
body: <p>I'm having difficulty figuring out how to assert with jsonPath in a JSON document response in spring mvc. Perhaps there's a better way of accomplishing this than using jsonPath for this particular scenario. I would like to validate that the links array has a  rel item of "self" and that "href" attribute of the object of "self" also has an "href" attribute which is equal to "/". The JSON response looks like this:</p>
  
  <pre><code> {  
     "links":[  
        {  
           "rel":[  
              "self"
           ],
           "href":"/"
        },
        {  
           "rel":[  
              "next"
           ],
           "href":"/1"
        }
     ]
  }
  </code></pre>
  
  <p>I tried this where I can see that it has rel [0] has self but I would prefer to not rely on where in the links array and rel array the self is and actually test what that href is at links[rel][self] is "/".
  Any ideas?</p>
  
  <pre><code> @Before
    public void setup() {
      MockitoAnnotations.initMocks(this);
      mockMvc = MockMvcBuilders.standaloneSetup(welcomeController).build();
    }
  
    @Test
    public void givenRootUrl_thenReturnLinkToSelf() throws Exception {
      mockMvc.perform(get("/")).andDo(print()).andExpect(status().isOk())
          .andExpect(jsonPath("$.links[0].rel[0].", is("self")));
    }
  </code></pre>
