java - Spring Boot maven jar无法运行

Question

我的 spring boot 应用程序可以用 idea 运行，但可以用 maven 打包，但 jar 无法运行! 这是一些异常消息:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSecurityConfig': Unsatisfied dependency expressed through method 'setContentNegotationStrategy' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$EnableWebMvcConfiguration': Unsatisfied dependency expressed through method 'setConfigurers' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter': Unsatisfied dependency expressed through constructor parameter 3; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.HttpMessageConvertersAutoConfiguration': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.web.HttpMessageConvertersAutoConfiguration$$EnhancerBySpringCGLIB$$fa131940]: Constructor threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mappingJackson2HttpMessageConverter' defined in class path resource [org/springframework/boot/autoconfigure/web/JacksonHttpMessageConvertersConfiguration$MappingJackson2HttpMessageConverterConfiguration.class]: Unsatisfied dependency expressed through method 'mappingJackson2HttpMessageConverter' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jacksonObjectMapper' defined in class path resource [org/springframework/boot/autoconfigure/jackson/JacksonAutoConfiguration$JacksonObjectMapperConfiguration.class]: Unsatisfied dependency expressed through method 'jacksonObjectMapper' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jacksonObjectMapperBuilder' defined in class path resource [org/springframework/boot/autoconfigure/jackson/JacksonAutoConfiguration$JacksonObjectMapperBuilderConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.http.converter.json.Jackson2ObjectMapperBuilder]: Factory method 'jacksonObjectMapperBuilder' threw exception; nested exception is java.lang.IllegalArgumentException: name

我的 pom.xml 有插件:

 <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>

我使用这个命令来打包:

mvn clean package

并使用java -jar target/security-0.0.1-SNAPSHOT.jar来运行这个.jar 该应用程序可以打包，但无法运行。 我应该如何修复它？

这是我的洞 pom.xml

这是 Maven 编译消息:

使用 Jackson2ObjectMapper‌​Builder，我使用 jpa 来节省时间并从 mysql 获取时间，如下所示:

@Entity
@Table(name="simulate_data")
public class SimulateData {
   ...
     @Temporal(TemporalType.TIME)
     @DateTimeFormat(pattern = "HH:mm:ss.SSSSSS")
     private Date  crawlingTime;
   ...
}

我该怎么办？

Answer 1

我已经找到错在哪里了! 我在 application.yml 中使用了 Jackson，如下所示:

spring:
  jackson:
    serialization: true
    date-format: HH:mm:ss.SSSSSS

我删除这段代码，jar就可以正常运行了。 但如果没有这段代码，我只是在 web html 中得到一个数字而不是时间字符串。 我应该如何获取时间字符串？
