Spring Data Rest 2.0.0.RELEASE以前使用RC1打破代码工作
我有一个项目，它正在使用Spring Data Rest。 我最初在我的pom.xml中有版本2.0.0.BUILD-SNAPSHOT ，但在我上次更新时，代码2.0.0.BUILD-SNAPSHOT并在访问大多数端点时开始抛出以下IllegalStateException ：
java.lang.IllegalStateException: No suitable resolver for argument [0] [type=org.springframework.http.converter.HttpMessageNotReadableException] HandlerMethod details: Controller

然后Spring Boot Actuate记录以下错误：
2014-02-28 07：58：54.986 ERROR 9232 — [nio-8080-exec-6] osbactuate.web.BasicErrorController：org.springframework.http.converter.HttpMessageNotWritableException：无法编写JSON :(是java.lang .NullPointerException）（通过引用链：org.springframework.hateoas.Resource [“content”]）; 嵌套exception是com.fasterxml.jackson.databind.JsonMappingException :(是java.lang.NullPointerException）（通过引用链：org.springframework.hateoas.Resource [“content”]）
如果我修改我的pom.xml以使用SDR版本2.0.0.RC1那么一切似乎都按预期工作。
我想解决这个问题，因为我一直在等待最新版本中包含的错误修复，但这个问题阻止了我升级。 有解决方法吗？ 堆栈跟踪甚至难以告诉问题在哪里，但仅根据时间我认为这个问题可能与此提交有关：
https://github.com/spring-projects/spring-data-rest/commit/3e5914d84f9708015b36a8840a25e9fa10a7f6ae
根据要求，依赖关系是：
spring-data-rest-webmvc 2.0.0.RELEASE
spring-boot-starter-web 1.0.0.BUILD-SNAPSHOT
spring-boot-starter-actuator 1.0.0.BUILD-SNAPSHOT
spring-boot-starter-security 1.0.0.BUILD-SNAPSHOT
spring-boot-starter-data-jpa 1.0.0.BUILD-SNAPSHOT
spring-boot-starter-shell-remote 1.0.0.BUILD-SNAPSHOT
spring-boot-starter-tomcat [提供]
spring-boot-starter-test 1.0.0.BUILD-SNAPSHOT
spring-security-ldap 3.2.0.RELEASE
似乎spring-boot-starter-jpa提供了spring-data-commons的旧版本而不是spring-data-rest-webmvc，但重新排序依赖关系以拉1.7.0.RELASE而不是1.7.0.RC1并没有似乎产生了影响。
这是一个已知和修复的错误，基本上掩盖了我们方面的jackson序列化问题。 该修复程序已经在2.0.1版本以及2.1 M1中。
随意尝试快照。
