我正在尝试将JSON对象转换为POJO，理想情况下，我的collection对象中将有一个对象列表（cluster个）。但是，JSON模式不使用列表，而是使用collection名称的映射，该映射是未知的，可能会更改。是否可以使用GSON将其转换为POJO列表？
有问题的JSON：
{
"responseHeader":{
"status":0,
"QTime":333},
"cluster":{
"collections":{
"collection1":{
"shards":{
"shard1":{
"range":"80000000-ffffffff",
"state":"active",
"replicas":{
"core_node1":{
"state":"active",
"core":"collection1",
"node_name":"127.0.1.1:8983_solr",
"base_url":"http://127.0.1.1:8983/solr",
"leader":"true"},
"core_node3":{
"state":"active",
"core":"collection1",
"node_name":"127.0.1.1:8900_solr",
"base_url":"http://127.0.1.1:8900/solr"}}},
"shard2":{
"range":"0-7fffffff",
"state":"active",
"replicas":{
"core_node2":{
"state":"active",
"core":"collection1",
"node_name":"127.0.1.1:7574_solr",

"router":{"name":"compositeId"},
"replicationFactor":"1",
"znodeVersion": 11,
"autoCreated":"true",
"configName" : "my_config",

您可以使用TypeAdapter将对象转换为对象列表，或者仅将org.springframework.web.HttpMediaTypeNotSupportedException
中的所有对象转换为@RequestMapping(value = "/v1/teste", method = RequestMethod.POST)
public Saida teste(final @RequestBody(required = true) Object objeto) {}
@EnableWebMvc
@WebAppConfiguration
@ContextConfiguration("classpath:test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)
public class IntegracaoTest {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void teste() throws Exception {
this.mockMvc.perform(post("/v1/teste")
.contentType(MediaType.APPLICATION_JSON).content("{}"))
.andDo(print()).andExpect(status().is(200));
}
}
<tx:annotation-driven />
<context:annotation-config />
<aop:aspectj-autoproxy />
<context:component-scan base-package="com.teste.*" />
<!-- Entity Manager -->
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath:persistence.xml" />
<property name="persistenceUnitName" value="teste" />
</bean>
<!-- Transaction Manager -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<jpa:repositories base-package="com.teste.repositories"/>
MockHttpServletRequest:
HTTP Method = POST
Request URI = /v1/teste
Parameters = {}
Headers = {Content-Type=[application/json]}
Handler:
Type = com.teste.rest.TesteController$$EnhancerBySpringCGLIB$$c0dc19e2
Async:
Was async started = false
Async result = null
Resolved Exception:
Type = org.springframework.web.HttpMediaTypeNotSupportedException
ModelAndView:
View name = null
View = null
Model = null
FlashMap:
MockHttpServletResponse:
Status = 415
Error message = null
Headers = {Accept=[application/octet-stream, */*, text/plain;charset=ISO-8859-1, */*, application/xml, text/xml, application/*+xml, application/x-www-form-urlencoded, multipart/form-data]}
Content type = null
Body =
Forwarded URL = null
Redirected URL = null
Cookies = []
，然后将其解析为cluster，像这样：

我建议您可以构建POJO模型，然后在导入数据后进行转换。
dotnet ef migrations add 'somename'
dotnet ef database update
：
stackoverflow/model/CoreNode.java package stackoverflow.model;
/**
* CoreNode
*/
public class CoreNode {
private String state;
private boolean leader;
private String core;
private String node_name;
private String base_url;
public CoreNode() {
super();
}
public String getState() {
return this.state;
}
public void setState(String state) {
this.state = state;
}
public boolean getLeader() {
return this.leader;
}
public void isLeader(boolean leader) {
this.leader = leader;
}
public String getCore() {
return this.core;
}
public void setCore(String core) {
this.core = core;
}
public String getNode_name() {
return this.node_name;
}
public void setNode_name(String node_name) {
this.node_name = node_name;
}
public String getBase_url() {
return this.base_url;
}
public void setBase_url(String base_url) {
this.base_url = base_url;
}
}
：
stackoverflow/model/Shard.java然后在您的主要功能中，对每个集合使用package stackoverflow.model;
import java.util.Map;
/**
* Shard
*/
public class Shard {
private String range;
private String state;
private Map<String, CoreNode> replicas;
public Shard() {
super();
}
public String getRange() {
return this.range;
}
public void setRange(String range) {
this.range = range;
}
public String getState() {
return this.state;
}
public void setState(String state) {
this.state = state;
}
public List<CoreNode> getReplicas() {
return this.replicas;
}
public void setReplicas(List<CoreNode> replicas) {
this.replicas = replicas;
}
}
结构。 （然后是Map<String, Shard>集合的结构）
然后，无论您希望将哪个地图作为列表，都可以进行操作（对于Map<String, Map<String, Shard>> for the generic而言）
Shard
