我使用JBoss 7.1.Final作为应用服务器，Oracle作为数据库使用。我们正在使用Spring框架3.x和Java 6.尝试传入一个字符串数组并将它们在存储过程中转换为varchars数组。我还没有找到一个很好的例子。如果您可以访问任何文档或以前的论坛帖子，请提供指针。我搜索过但没找到一个似乎适用的。
存储过程定义为：
CREATE OR REPLACE PROCEDURE GET_TEST_CONTENTS
(IN_RR_ARRAY IN RR_ARRAY,
IN_ORDER_STATE IN VARCHAR2,
OUT_FLAG OUT VARCHAR2,
OUT_RETURN_CODE OUT VARCHAR2,
OUT_RETURN_DESC OUT VARCHAR2,
OUT_RETURN_TYPE OUT VARCHAR2,
OUT_RETURN_VAL OUT NUMBER
)
类型RR_ARRAY定义为： 创建或替换 键入RR_ARRAY作为varchar2（15）的表;
在我的java代码中，我有：
jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.setResultsMapCaseInsensitive(true);
this.getTestContents = new SimpleJdbcCall(jdbcTemplate)
.withCatalogName("STAR")
.withoutProcedureColumnMetaDataAccess()
.withProcedureName("GET_TEST_CONTENTS")
.declareParameters(
new SqlParameter("IN_RR_ARRAY", OracleTypes.ARRAY,
"RR_ARRAY"),
new SqlParameter("IN_ORDER_STATE", OracleTypes.VARCHAR), new SqlOutParameter("OUT_FLAG",
OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_VAL", OracleTypes.INTEGER),
new SqlOutParameter("OUT_RETURN_CODE", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_DESC", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_TYPE", OracleTypes.VARCHAR));
//I get a different error here so creating new connection for testing
//conn = jdbcTemplate.getDataSource().getConnection();
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection(jdbcURL, user, passwd);
ArrayDescriptor desc = new ArrayDescriptor("STAR.RR_ARRAY", conn);
ARRAY arr = new ARRAY(desc, conn, testArray); // testArray is just
// String[] with 2 values
Map<String, Object> hm = new HashMap<String, Object>();
hm.put("IN_RR_ARRAY", arr);
hm.put("IN_ORDER_STATE", stateCode);
hm.put("OUT_FLAG", Types.VARCHAR);
hm.put("OUT_RETURN_CODE", Types.VARCHAR);
hm.put("OUT_RETURN_DESC", Types.VARCHAR);
hm.put("OUT_RETURN_TYPE", Types.VARCHAR);
SqlParameterSource in = new MapSqlParameterSource().addValues(hm);
Map out = getTestContents .execute(in);
返回的堆栈跟踪是：

我找到了解决方法。现在我使用这个字符串列表：
List<String> ndcList;
我将数组参数从OracleTypes.ARRAY更改为java.sql.stypes.ARRAY并在数组名称上指定了模式前缀。并更改了代码并在底部创建了一些新的便捷方法。
我需要包装连接，并且必须将此依赖项添加到我的pom：
<dependency>
<groupId>jboss</groupId>
<artifactId>jboss-common-jdbc-wrapper</artifactId>
<version>3.2.3</version>
</dependency>
----方法代码从这里开始------------
jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.setResultsMapCaseInsensitive(true);
this.getTestContents = new SimpleJdbcCall(jdbcTemplate)
.withCatalogName("STAR")
.withoutProcedureColumnMetaDataAccess()
.withProcedureName("GET_TEST_CONTENTS")
.declareParameters(
new SqlParameter("IN_RR_ARRAY", java.sql.types.ARRAY,
"STAR.RR_ARRAY"),
new SqlParameter("IN_ORDER_STATE", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_FLAG",
OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_VAL", OracleTypes.INTEGER),
new SqlOutParameter("OUT_RETURN_CODE", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_DESC", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_TYPE", OracleTypes.VARCHAR));
Map<String, Object> hm = new HashMap<String, Object>();
hm.put("IN_RR_ARRAY", new ScriptArray(ndcList));
hm.put("IN_ORDER_STATE", stateCode);
hm.put("OUT_FLAG", Types.VARCHAR);
hm.put("OUT_RETURN_CODE", Types.VARCHAR);
hm.put("OUT_RETURN_DESC", Types.VARCHAR);
hm.put("OUT_RETURN_TYPE", Types.VARCHAR);
SqlParameterSource in = new MapSqlParameterSource().addValues(hm);
Map out = getTestContents .execute(in);
---- method code ends here------------
public class ScriptArray extends AbstractSqlTypeValue {
private List<String> values;
public ScriptArray(List<String> values) {
this.values = values;
}
public Object createTypeValue(Connection con, int sqlType,
String typeName) throws SQLException {
oracle.jdbc.OracleConnection wrappedConnection = con

ArrayDescriptor desc = new ArrayDescriptor(typeName, con);
return new ARRAY(desc, con,

与一天的类似问题作斗争。 This article帮助了我。 这是代码备份，以防页面不可用：
-- custom type
create or replace TYPE "MY_TYPE"
as object(name varchar(255),
value varchar(255))
-- array of MY_TYPE
create or replace
TYPE "MY_ARRAY"
as table of MY_TYPE
-- echo like SP, doesn't do too much
create or replace
procedure foo(
i_array in MY_ARRAY,
o_array out MY_ARRAY)
as
begin
o_array := MY_ARRAY();
for i in 1 .. i_array.count loop
o_array.extend;
o_array(i) := MY_TYPE(i_array(i).name, i_array(i).value);
end loop;
end;

return new ARRAY(descriptor, con, values);
}
});
Map<?, ?> result = storedProcedure.execute(params);
if ((!result.containsKey(O_ARRAY) || result.get(O_ARRAY) == null)) {
return null;
}
try {
Object[] resultArray = (Object[]) ((ARRAY) result.get(O_ARRAY)).getArray();
return Arrays.copyOf(resultArray, resultArray.length, MyType[].class);
} catch (SQLException e) {
throw new DataRetrievalFailureException("Unable to retrieve array", e);

我看了互联网，很难将其与许多人提供的解决方案一起使用。..这是工作代码示例..在pom.xml中创建此依赖项。
<dependency>

CREATE OR REPLACE TYPE employee_type
AS OBJECT (EMPNO number(12), FNAME varchar2(60), LNAME varchar2(60), EMAIL varchar2(120));

春季的SqlStructArrayValue在OracleConnection强制转换方面存在一些问题，因此我创建了自己的类似于它们的
。import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Struct;
import oracle.jdbc.OracleConnection;
import org.springframework.dao.InvalidDataAccessApiUsageException;
import org.springframework.data.jdbc.support.oracle.SqlStructArrayValue;
import org.springframework.data.jdbc.support.oracle.StructMapper;
/**
*
* @author rsharma
*/
public class OracleSqlStructArrayValue<T> extends SqlStructArrayValue<T> {
private T[] values;
/**
* The object that will do the mapping *
*/
private StructMapper<T> mapper;
/**
* The type name of the STRUCT *
*/
private String structTypeName;
/**
* The type name of the ARRAY *
*/
private String arrayTypeName;
public OracleSqlStructArrayValue(T[] values, StructMapper<T> mapper, String structTypeName) {
super(values, mapper, structTypeName);
this.values = values;
this.mapper = mapper;
this.structTypeName = structTypeName;
}
public OracleSqlStructArrayValue(T[] values, StructMapper<T> mapper, String structTypeName, String arrayTypeName) {
super(values, mapper, structTypeName, arrayTypeName);
this.values = values;
this.mapper = mapper;
this.structTypeName = structTypeName;
this.arrayTypeName = arrayTypeName;
}
@Override
protected Object createTypeValue(Connection conn, int sqlType, String typeName) throws SQLException {
if (typeName == null && arrayTypeName == null) {
throw new InvalidDataAccessApiUsageException(
"The typeName for the array is null in this context. Consider setting the arrayTypeName.");
}
Struct[] structValues = new Struct[values.length];
for (int i = 0; i < values.length; i++) {
structValues[i] = mapper.toStruct(values[i], conn, structTypeName);
}
OracleConnection oracleConn = (OracleConnection) conn;
return oracleConn.createOracleArray(typeName != null ? typeName : arrayTypeName, structValues);
}
}
现在在您的DAO类中，执行以下操作...
public class EmployeeDAO {
private static final Logger logger = LoggerFactory.getLogger(EmployeeDAO.class);
@Autowired
private DataSource dataSource;
private JdbcTemplate jdbcTemplate;
private SimpleJdbcCall saveEmployeesArrayCall;
@PostConstruct
private void postConstruct() {
jdbcTemplate = new JdbcTemplate(dataSource);
this.saveEmployeesArrayCall =
new SimpleJdbcCall(dataSource).withProcedureName(SQLConstants.SAVE_EMPLOYEES_STORE_PROC)
.withoutProcedureColumnMetaDataAccess()
.declareParameters(new SqlParameter("p_emp_insert_array", Types.ARRAY, SQLConstants.EMPLOYEE_OBJ_TABLE_TYPE));
}
public void saveEmployees(List<Employee> employees) {
Map<String, Object> in = new HashMap<>();
in.put("p_emp_insert_array", new OracleSqlStructArrayValue<>(employees.toArray(new Employee[0]), new EmployeeStructMapper(), SQLConstants.EMPLOYEE_OBJ_TYPE));
saveEmployeesArrayCall.execute(in);
}
}
