Apache Tomcat は 19KB を超える POST リクエストを拒否し、400 BAD REQUEST を返します。

Question

Apache にデプロイされた Spring Boot アプリケーショントムキャット9 19kb を超える投稿リクエストを拒否します。

のブックコントローラー:

@CrossOrigin(origins = "*", maxAge = 3600)
@RestController
@RequestMapping("/api/v1/book")
@AllArgsConstructor
public class BookController {
    private final static Logger logger = LoggerFactory.getLogger(BookController.class);
    
    private final BookServices bookServices;
    private final BookRepository bookRepository;
    
    @PostMapping("/add")  @ResponseStatus(code = HttpStatus.CREATED)
    public void addBook(@Valid @RequestBody BookModel bookModel) throws SanprException {
        try {
            logger.info("success...");
            bookServices.addBook(bookModel);
        } catch (Exception e) {
            StringBuilder message = new StringBuilder("Failed...");
            throw new SanprException(message.toString(), e, Boolean.FALSE, Boolean.TRUE);
        }
    }
}  

のブックモデルクラス ：

@Data
@NoArgsConstructor
@AllArgsConstructor
public class BookModel {    
        @Id
        private long id;
        private String title;
        private boolean isPublish;
        private boolean isDuplicated;
        private MediaModel background;
        private String pdfFile;
        private String description;
        private List<TableContentsModel> tableContents;
        private GlobalReferentialModel level;
        private GlobalReferentialModel type;

}
