我正在使用无状态弹簧安全性,但在注册的情况下我想禁用spring security.I禁用使用
antMatchers("/api/v1/signup").permitAll().
但它不起作用,我收到以下错误:
message=An Authentication object was not found in the SecurityContext, type=org.springframework.security.authentication.AuthenticationCredentialsNotFoundException
我认为这意味着Spring安全过滤器正在运行
我的网址顺序总是"/ api/v1"
我的春天配置是
@Override
protected void configure(HttpSecurity http) throws Exception {
http.
csrf().disable().
sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
and().
authorizeRequests().
antMatchers("/api/v1/signup").permitAll().
anyRequest().authenticated().
and().
anonymous().disable();
http.addFilterBefore(new AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter.class);
}
我的验证过滤器是
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = asHttp(request);
HttpServletResponse httpResponse = asHttp(response);
String username = httpRequest.getHeader("X-Auth-Username");
String password = httpRequest.getHeader("X-Auth-Password");
String token = httpRequest.getHeader("X-Auth-Token");
String resourcePath = new UrlPathHelper().getPathWithinApplication(httpRequest);
try { …我正在尝试创建并使用enumMongoose中的类型.我检查了一下,但是我没有得到正确的结果.我enum在我的程序中使用如下:
我的架构是:
var RequirementSchema = new mongoose.Schema({
status: {
type: String,
enum : ['NEW', 'STATUS'],
default: 'NEW'
},
})
但我在这里有点困惑,我怎么能把enum类似的价值放进去Java NEW("new").如何enum根据它的可枚举值将数据保存到数据库中.我在express node.js中使用它.
我正在开发spring boot应用程序.我必须为它编写测试用例.我以前没有写过测试用例,所以有人建议使用spock框架.我探索了spock,我认为它与groovy语言更相关.
我可以为我的春季应用程序编写spock测试用例吗？
如果是这样,那么你能否建议我更好地记录"如何在春季启动应用程序中使用它"？
我正在研究mongodb的地理空间查询,我已经在mongo控制台上执行了以下查询
db.items.find(
{
location:
{ $near :
{
$geometry: { type: "Point", coordinates: [77.026638, 28.459497 ] },
$maxDistance: 10000
}
}
}
)
但是如何使用spring数据mongodb标准编写此查询？
我尝试使用以下标准,但它无法正常工作
Criteria criteria = Criteria.where("location").near(new Point(77.026638, 28.459497)).maxDistance(1000);
Query query = new Query(criteria);
System.out.println(mongoTemplate.find(query, Item.class));

加载opencv
@SpringBootApplication
@EnableScheduling
public class SamepinchApplication extends SpringBootServletInitializer{
static {
try{
nu.pattern.OpenCV.loadShared();
System.loadLibrary(org.opencv.core.Core.NATIVE_LIBRARY_NAME);

System.out.println("Open CV Library could not load due to " + exception.getCause());
}
}
public static void main(String[] args) {

}
}
Maven 依赖
<dependency>
<groupId>nu.pattern</groupId>

请帮助我，加载 opencv 或其他本机库的好做法是什么？
当我试图订阅mqtt客户端时,我得到"java.io.eof"异常.我正在使用eclipse paho库并使用mosquitto broker.我没有得到任何答案,所以请帮助我为什么会这样？
Mqtt连接和订阅
我正在使用此代码连接和订阅mosquitto
private void buildClient(String clientId){
log.debug("Connecting... "+clientId);
try {
mqttClient = new MqttClient(envConfiguration.getBrokerUrl(), clientId,new MemoryPersistence());
System.out.println(mqttClient.isConnected());
} catch (MqttException e) {
log.debug("build client stopped due to "+e.getCause());
}
chatCallback = new ChatCallback(this.userService,this);
mqttClient.setCallback(chatCallback);
mqttConnectOptions = new MqttConnectOptions();
mqttConnectOptions.setCleanSession(true);
}
@Override
public void connect(String clientId,String topic) {
try{
if(mqttClient == null || !mqttClient.getClientId().equals(clientId)){
buildClient(clientId);
mqttClient.connect(mqttConnectOptions);
subscribe(clientId,topic);
}
}catch (Exception e) {

"createdDate": [
2020,
8,
31,
0,
0,
0,
80000000
]
如Spring Boot中的JSON Java 8 LocalDateTime 格式所述，Spring Boot 2 已经在类路径上默认设置了 jackson-datatype-jsr310:2.10.3。我希望日期在整个项目中以 json 表示为 2020-03-31:00。第一个解决方案在上面的链接中不起作用。在那之后，我尝试了 @JsonSerialize 注释并且它有效，但我不想应用于每个类。所以也试图覆盖对象映射器但它没有用
@Primary
@Bean
public ObjectMapper objectMapper() {
ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);

SimpleModule module = new SimpleModule("my custom date serializer");
module.addSerializer(LocalDateTime.class,new LocalDateTimeSerializer());
mapper.registerModule(module);
return mapper;
}
还尝试自定义 Jackson2ObjectMapperBuilder，但仍然有数组格式的日期
