SpringBoot-HttpMessageNodeTableException:JSON解析错误：java.net.SocketTimeoutException

我的代码抛出一个异常，如下所示

JSON parse error: java.net.SocketTimeoutException; nested exception is com.fasterxml.jackson.databind.JsonMappingException: java.net.SocketTimeoutException (through reference chain: java.util.ArrayList[9])
org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: java.net.SocketTimeoutException; nested exception is com.fasterxml.jackson.databind.JsonMappingException: java.net.SocketTimeoutException (through reference chain: java.util.ArrayList[9])

我的spring启动版本是2.1.7.0版本，嵌入式tomcat用于运行应用程序。 我还设置了属性

server.connection timeout=30s

我几乎到处搜索，找不到这个问题的根本原因。我还捕获此异常并将其打印在日志中，并将响应作为BAD_请求返回

此异常是间歇性引发的，此时我的生产服务器消耗了80%以上的CPU和内存

这实际上是一个POST请求，请求主体验证如下

    @RequestMapping( value = "/save", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE )
    public SaveDto create( @RequestBody @Valid SaveDto saveDto,
        HttpServletResponse response, HttpServletRequest request )
    {
      //my logic
    }

@JsonInclude( JsonInclude.Include.NON_NULL )
public class SaveDto
{
    private String id;
    @Size( min = 1 )
    @Valid
    private List< SaveEntryDto > saveLogEntries;
}

public class SaveEntryDto implements Comparable<SaveEntryDto> {
    private String id;
    private String idRef;
    private WER wer;
    @Min(0)
    @Max(1440)
    private Integer kjh;
    @Min(0)
    @Max(1440)
    private Integer gfd;
    private String abc;
    private Double def;
    private String ghi;
    private Boolean klm = Boolean.FALSE;
    private Boolean hug;
    private Boolean qwe;
    private Double azx;
    private Double xds;
    private Boolean cvf = Boolean.FALSE;
    private Boolean bgh = Boolean.FALSE;
    private String nmj;
    private Boolean rgh;
    private Boolean jkh;
    private Boolean mkl = Boolean.FALSE;
    private Boolean wed = Boolean.FALSE;
    private Long ftu;

    private Long iop;
    private Double poi;
    private Boolean uyt = Boolean.FALSE;
    private Boolean rew = Boolean.FALSE;
    private String qsd;
}

我的存盘如下

    @RequestMapping( value = "/save", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE )
    public SaveDto create( @RequestBody @Valid SaveDto saveDto,
        HttpServletResponse response, HttpServletRequest request )

您发送到此端点的有效负载有多大？您能否确认您的依赖项中的嵌入式tomcat版本是什么？我认为应该是9.0.31。我遇到了类似的问题，发现Tomcat9.0.31有一个调试导致了它。这里是链接。该缺陷在9.0.33版本中已修复。它对我有用，你能试试吗？@P.J.Meisch有效载荷没有限制。在添加了一些改进的日志之后，我们可以看到大多数请求有时会抛出此异常。即使是一个非常小的负载处理api。@aks我会尝试更新版本并让您know@aks我的版本是9.0.22
