JobParametersConverter
public class DefaultJobParametersConverter extends java.lang.Object implements JobParametersConverter
Converter forJobParametersinstances using a simple naming convention for property keys. Key names that are prefixed with a - are considered non-identifying and will not contribute to the identity of aJobInstance. Key names ending with "(<type>)" where type is one of string, date, long are converted to the corresponding type. The default type is string. E.g.schedule.date(date)=2007/12/11 department.id(long)=2345
The literal values are converted to the correct type using the default Spring strategies, augmented if necessary by the custom editors provided.
If you need to be able to parse and format local-specific dates and numbers, you can inject formatters (setDateFormat(DateFormat)andsetNumberFormat(NumberFormat)).- 作者:

方法详细资料
getJobParameters
public JobParameters getJobParameters(@Nullable java.util.Properties props)
Check for suffix on keys and use those to decide how to convert the value.- 指定者:
getJobParameters在接口中JobParametersConverter- 参数:
props- the runtime parameters in the form of String literals.- 返回:
- a
JobParametersproperties converted to the correct types. - 抛出:
java.lang.IllegalArgumentException- if a number or date is passed in that cannot be parsed, or cast to the correct type.- 另请参阅:
JobParametersConverter.getJobParameters(java.util.Properties)
getProperties
public java.util.Properties getProperties(@Nullable JobParameters params)
Use the same suffixes to create properties (omitting the string suffix because it is the default). Non-identifying parameters will be prefixed with theNON_IDENTIFYING_FLAG. However, since parameters are identifying by default, they will not be prefixed with theIDENTIFYING_FLAG.- 指定者:
getProperties在接口中JobParametersConverter- 参数:
params- theJobParametersinstance to be converted.- 返回:
- a representation of the parameters as properties
- 另请参阅:
JobParametersConverter.getProperties(org.springframework.batch.core.JobParameters)
setDateFormat
public void setDateFormat(java.text.DateFormat dateFormat)
Public setter for injecting a date format.- 参数:
dateFormat- aDateFormat, defaults to "yyyy/MM/dd"
setNumberFormat
public void setNumberFormat(java.text.NumberFormat numberFormat)
Public setter for theNumberFormat. Used to parse longs and doubles, so must not contain decimal place (e.g. use "#" or "#,###").- 参数:
numberFormat- theNumberFormatto set
