Spring Roo Tomcat问题

Question

我在Spring Roo和Tomcat中遇到了一个令人讨厌的问题。 继Spring Roo的比萨饼店教程中，我已发出以下命令：

project com.springsource.pizzashop 

// Setup JPA persistence using EclipseLink and H2 
jpa setup --provider ECLIPSELINK --database H2_IN_MEMORY 

// Create domain entities 
entity jpa --class ~.domain.Base --testAutomatically 
field string --fieldName name --sizeMin 2 --notNull 

entity jpa --class ~.domain.Topping --testAutomatically 
field string --fieldName name --sizeMin 2 --notNull 

entity jpa --class ~.domain.Pizza --testAutomatically 
field string --fieldName name --notNull --sizeMin 2 
field number --fieldName price --type java.math.BigDecimal 
field set --fieldName toppings --type ~.domain.Topping 
field reference --fieldName base --type ~.domain.Base 

entity jpa --class ~.domain.PizzaOrder --testAutomatically --identifierType ~.domain.PizzaOrderPk 
field string --fieldName name --notNull --sizeMin 2 
field string --fieldName address --sizeMax 30 
field number --fieldName total --type java.math.BigDecimal 
field date --fieldName deliveryDate --type java.util.Date 
field set --fieldName pizzas --type ~.domain.Pizza 

field string --fieldName shopCountry --class ~.domain.PizzaOrderPk 
field string --fieldName shopCity 
field string --fieldName shopName 

// Offer JSON remoting for all domain types trough Spring MVC 
json all --deepSerialize 
web mvc json setup 
web mvc json all 

web mvc setup 
web mvc all --package ~.web 

然后在命令行我打电话：

mvn tomcat:run 

当我在比萨实体添加一个新的领域，我得到的错误：

编辑：只是有点澄清。当我停止服务器并再次启动时，一切正常，并且通常会添加该字段。我试图用roo命令添加字段并修改java代码。

有什么建议吗？

干杯

Answer 1

由于Xaerxess建议：在你application.properties（应该是project-root/src/main/WEB-INF/i18n/）丢失

label_com_springsource_pizzashop_domain_pizza_newfield=Label for newfield 

这些标签至少，如果你使用Web MVC框架的弹簧产生实体领域中产生的线Roo模块（尽管在web json中不能说），但是在我当前的项目中只有默认的语言环境（可能是项目启动时的配置错误）。

有点神秘的是，你的代码不显示字段的生成newfield。你是否在你的实体中手动引入了这个字段？
