org.springframework.beans.factory.BeanCreationException：创建名为“XXX”的bean时出错

Question

我一直在尝试在我的tomcat服务器上部署我的项目，但显然，每次我尝试启动服务器时，都会在我的catalina日志中出现此错误：

Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 
'mnpTranslationServiceImpl' defined in URL [file:/opt/tomcat/webapps/axis2/WEB-INF/springjdbc.xml]: 
Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'mnpTranslationDAO' of bean class [com.e_horizon.jdbc.mnpTranslation.mnpTranslationServiceImpl]: 
Bean property 'mnpTranslationDAO' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

这是我的bean.xml，我将其命名为springjdbc.xml

这是DAO文件，错误表示不可写：

package com.e_horizon.jdbc.mnpTranslation;

import java.util.HashMap;
import java.util.Map;

import org.springframework.jdbc.core.RowMapper;
import org.springframework.jdbc.core.simple.SimpleJdbcInsert;

import com.e_horizon.www.jdbc.common.BaseDAO;

public class mnpTranslationDAO extends BaseDAO {
    private SimpleJdbcInsert jdbcCall;

    public static String TABLE = "MNP_TRANSLATION";
    public static String FIELD_MSISDN = "msisdn";
    public static String FIELD_ROUTING_NUMBER = "routing_number";
    public static String FIELD_LAST_UPDATE = "last_update";
    public static String FIELD_ACTION = "action";

    protected RowMapper getObjectMapper () {
        return new mnpTranslationMapper();
    }

    public void save (mnpTranslation mnp) {
        this.jdbcCall = this.getSimpleJdbcInsert().withTableName(TABLE);
        Map<String, Object> parameters = new HashMap<String, Object>();

        parameters.put(FIELD_MSISDN, mnp.getMsisdn());
        parameters.put(FIELD_ROUTING_NUMBER, mnp.getRouting_number());
        parameters.put(FIELD_LAST_UPDATE, mnp.getLast_update());
        parameters.put(FIELD_ACTION, mnp.getAction());

        jdbcCall.execute(parameters);
    }
}

添加包含setter和getter的模型（mnpTranslation.java）：

package com.e_horizon.jdbc.mnpTranslation;

import java.sql.Timestamp;

public class mnpTranslation {
private String msisdn;
private String routing_number;
private Timestamp last_update;
private String action;

    public void setMsisdn (String msisdn) {
        this.msisdn = msisdn;
    }

    public String getMsisdn () {
        return this.msisdn;
    }

    public void setRouting_number (String routing_number) {
        this.routing_number = routing_number;
    }

    public String getRouting_number () {
        return this.routing_number;
    }

    public void setLast_update (Timestamp last_update) {
        this.last_update = last_update;
    }

    public Timestamp getLast_update () {
        return this.last_update;
    }

    public void setAction (String action) {
        this.action = action;
    }

    public String getAction () {
        return this.action;
    }
}

[edit]我正在添加其余的java文件，这样你就可以看到我正在处理的更多内容。非常感谢您查看此内容。

mnpTranslationService.java：

package com.e_horizon.jdbc.mnpTranslation;

public abstract interface mnpTranslationService {
    public abstract void save (mnpTranslation mnp);
}

mnpTranslationServiceImpl.java：

package com.e_horizon.jdbc.mnpTranslation;

public class mnpTranslationServiceImpl {
    private mnpTranslationDAO mnpTranslationDAO;

    public void save (mnpTranslation mnp) {
        this.mnpTranslationDAO.save(mnp);
    }
}

mnpTranslationMapper.java：

package com.e_horizon.jdbc.mnpTranslation;

import java.sql.ResultSet;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

public class mnpTranslationMapper implements RowMapper {
    public Object mapRow (ResultSet result, int dex) throws SQLException {
        mnpTranslation mnp = new mnpTranslation();

        mnp.setMsisdn(result.getString("msisdn"));
        mnp.setRouting_number(result.getString("routing_number"));
        mnp.setLast_update(result.getTimestamp("last_update"));
        mnp.setAction(result.getString("action"));

        return mnp;
    }
}

错误消息指出问题出在您的mnpTranslationServiceImpl课程中。

参见错误消息

  

Bean property＆＃39; mnpTranslationDAO＆＃39;不可写或具有无效的setter方法。 setter的参数类型是否与getter的返回类型匹配？
