In every hibernate mapping files, we used to denote the “type” of the mapping variable. This type is actually known as Hibernate mapping types.
These are very much different from SQL database types as well as Java data types. Here you can find a list of Hibernate mapping types. Source : here

integer, long, short

Java primitives or wrapper classes to appropriate (vendor-specific) SQL column types.

float, double

Java primitives or wrapper classes to appropriate (vendor-specific) SQL column types.

character, byte

Java primitives or wrapper classes to appropriate (vendor-specific) SQL column types.

boolean, yes_no, true_false

Alternative encodings for a Java boolean or java.lang.Boolean

string

java.lang.String to VARCHAR (or Oracle VARCHAR2).

date, time, timestamp

java.util.Date and its subclasses to SQL types DATE, TIME and TIMESTAMP (or equivalent).

calendar, calendar_date

java.util.Calendar to SQL types TIMESTAMP and DATE (or equivalent).

big_decimal, big_integer

java.math.BigDecimal and java.math.BigInteger to NUMERIC (or Oracle NUMBER).

locale, timezone, currency

java.util.Locale, java.util.TimeZone and java.util.Currency to VARCHAR (or Oracle VARCHAR2). Instances of Locale and Currency are mapped to their ISO codes. Instances of TimeZone are mapped to their ID

class

java.lang.Class to VARCHAR (or Oracle VARCHAR2). A Class is mapped to its fully qualified name.

binary

Maps byte arrays to an appropriate SQL binary type.

text

Maps long Java strings to a SQL CLOB or TEXT type.

serializable

Maps serializable Java types to an appropriate SQL binary type. You may also indicate the Hibernate type serializable with the name of a serializable Java class or interface that does not default to a basic type.

clob, blob

Type mappings for the JDBC classes java.sql.Clob and java.sql.BlobThese types may be inconvenient for some applications, since the blob or clob object may not be reused outside of a transaction. (Furthermore, driver support is patchy and inconsistent.)

Unitils is an open source library aimed at making unit testing easy and maintainable. Unitils builds further on existing libraries like DBUnit and EasyMock and integrates with JUnit and TestNG. This article will help you to test Spring- hibernate applications easily using unitles.

 The Spring IDE team has released the latest version of Spring IDE, which includes great visualizing support to increase productivity. Here is the text from official spring site.

The new features includes the highly-anticipated Spring Web Flow graphical visualizer and editor. The new support allows developers to edit XML-based flow definitions graphically, and enables greater productivity and communication with end users.

In addition to the graphical piece, Spring IDE 2.0 M3 also delivers a Web Flow XML editor that provides content assist and semantic validation to improve the quality of your flow definitions. : Source: www.springframework.org
